The use of copper for reducing nosocomial infections or healthcare-acquired infections (HAI) has been carried out in intensive care units (ICU) by replacing some objects generally made of stainless steel or other materials with solid pieces of copper. The authors’ proposal for a sustainable use of copper consists of introducing it in a lamina + adhesive format. This proposal has been tested in an ICU at the Ceuta Hospital in Spain. It has been found to provide an equally efficient solution as antibacterial material than the usual solid format, but with only a layer of 50 microns of copper, which is a high-cost and limited resource. After that intervention, some improvements are also proposed: a standardization of the pieces chosen to cover with a lamina of copper for saving material; and another method of replacement aiming to lower the time that the ICU cannot be used. To ensure that the proposed bonding method is harmless to human health and the adhesive does not interfere with the indoor environment by releasing toxic chemicals, the lamina + adhesive sheet has been further tested. The results and proposals are briefly shown.

Zeolite synthesis using faujasite-type (FAU) zeolites as the starting silica/alumina source in the presence of various organic structure-directing agents (OSDAs) with cyclic alkylammonium structures was investigated. The obtained zeolite phases strongly depended on the structure of the OSDA and the Si/Al ratio of the starting FAU. Zeolites with different framework structures, such as BEA, MFI, CHA, and LEV, were obtained. Among the used OSDAs, methylpropylpyrrolidinium, butylmethylpyrrolidinium, and methylpropylpiperidinium effectively produced nanosized BEA and MFI zeolites, whereas dimethylpiperidinium and cyclohexyltrimethylammonium produced CHA and LEV zeolites, respectively. The nanosized MFI and BEA zeolites obtained through zeolite hydrothermal conversion exhibited remarkably smaller particle sizes and higher external surface area as compared to those of the conventional MFI and BEA zeolite samples synthesized using tetrapropylammonium and tetraethylammonium, respectively. We also found that the highly crystalline nanosized BEA and MFI zeolites exhibited better catalytic performance in the dehydration of benzyl alcohol to benzyl ether as compared to the conventional zeolites with large particle sizes. In addition, nanosized MFI zeolites, synthesized using FAU as a starting material and cyclic ammonium compounds, showed catalytic activities superior to those of the nano sized MFI zeolites synthesized from amorphous starting materials and cyclic ammonium compounds.

A novel high-performance liquid chromatography (HPLC) multifunctional immobilized chiral stationary phase was prepared by bonding dialdehyde microcrystalline cellulose to aminosilica via Schiff base reaction and then derivatized with 3,5-dimethylphenyl isocyanate. The HPLC multifunctional immobilized chiral stationary phase could not only achieve chiral separation but also achieve achiral separation. Chiral separation evaluation showed that 1-(1-naphthyl)ethanol and mandelonitrile got separation in normal phase (NP) mode. Ranolazine, benzoin ethyl ether, metalaxyl, and diclofop were successfully separated in reversed phase (RP) mode. Aromatic compounds such as polycyclic aromatic hydrocarbons (PAHs), anilines, and aromatic acids were selected as analytes to investigate the achiral separation performance of the multifunctional immobilized chiral stationary phase in NP and RP modes. The achiral separation evaluation showed that six PAHs could get good separation within 10 minutes in NP mode. Four aromatic acids were well separated in RP mode. The retention mechanism of aromatic compounds on the stationary phase was discussed, founding that pi-pi interaction, pi-pi electron-donor-acceptor (EDA) interaction, and hydrogen bonding interaction played important roles during the achiral separation process. This multifunctional immobilized chiral stationary phase had the advantages of simple bonding steps, short reaction time, and no need for space arm.

Expanding the toolbox of C-H functionalization reactions applicable to the late-stage modification of complex molecules is of interest in medicinal chemistry, wherein the preparation of structural variants of known pharmacophores is a key strategy for drug development. One manifold for the functionalization of aromatic molecules utilizes diazo compounds and a transition-metal catalyst to generate a metallocarbene species, which is capable of direct insertion into an aromatic C-H bond. However, these high-energy intermediates can often require directing groups or a large excess of substrate to achieve efficient and selective reactivity. Herein, we report that arene cation radicals generated by organic photoredox catalysis engage in formal C-H functionalization reactions with diazoacetate derivatives, furnishing sp(2)-sp(3) coupled products with moderate-to-good regioselectivity. In contrast to previous methods utilizing metallocarbene intermediates, this transformation does not proceed via a carbene intermediate, nor does it require the presence of a transition-metal catalyst.

In this paper, the catalytic behaviour of carbonaceous system (Ccs) functionalized with -SO3H groups were studied in the etherification of refined (Gly) and crude glycerol (GlyC), with benzyl alcohol (BA). This Ccs was obtained by a synthetic method with low energetic cost in only 24 h. Its catalytic activity and selectivity were studied varying the catalyst percentage (2.5, 5 and 10 wt.%), the initial reactant molar ratio and temperature (between 80 and 120 degrees C). A very good catalytic performance was achieved (97 % conversion after 360 min of reaction), at 120 degrees C, Gly:BA = 3:1 and 10 wt.% of Ccs. The high activity can be attributed to high acid site density (6.4 mmol H+/g), that also allowed us to working at lower reaction temperature (100 degrees C) and with less catalyst concentration (2.5 wt.%), without observing significant loss in BA conversion. Monoether (ME1) was the major product of the reaction with 72 % selectivity. The material can be reused and still gives a notable conversion of BA (about 43 %) after three successive reuses. Finally, the Ccs was active and selective to the desired products in the etherification of crude glycerol (GlyC) derived of biodiesel industry. An important BA conversion (45 %) was obtained only reducing the water content of GlyC and without carrying out any other purification and/or neutralization treatment.

Raising the capability of supporting and suppressing the leaching possibility to a very insignificant level has still remained challenging for some class of transition metals, i.e. Ni2+. Here we present the covalent functionalisalon of macrocyclic ligand, 4,13-diaza-18-crown-6 (kryptofix 22), on the surface of carbon nanotube (CNT), leading to a unique adsorptive capability for supporting Ni2+. This material was incorporated as a promising catalyst in coupling reactions including C-C, CN, and CO- – cross-coupling reactions. We demonstrate that the kryptofix 22 functionalisation on the surface of CNT has a key role in the enhancement of the adsorption capability Ni2+ and subsequent catalytic activity. We further prove that this ligand causes a significant boost in the recyclability of the reactions due to the extremely trivial Ni2+ leaching from the CNT’s surface during the reactions.

A green recyclable cellulose-supported Pd(salen)-type catalyst was synthesized through sequential three steps: chlorination with thionyl chloride, modification by ethylenediamine, and the formation of Schiff base with salicylaldehyde to immobilize palladium chloride through multiple binding sites. This novel heterogeneous cellulosic Pd(salen)-type catalytic complex was fully characterized by FT-IR, SEM, TEM, XPS, ICP-AES and TG. The traditional cross-coupling chemistry, such as Suzuki, Heck, Sonogashira, Buchwald-Hartwig amination and etherification, was then investigated in the presence of the above cellulose-palladium nanoparticle. Studies have shown that the synthesized catalyst shows high activity and efficiency for all types of transformations, providing the corresponding carbon-carbon or carbon-heteroatom coupling products in a general and mild manner. Furthermore, the catalyst demonstrates high to excellent yields and is easily recycled by simple filtration for up to twelve cycles without any significant loss of catalytic activity. [GRAPHICS] .

In this work, 1,4-diphenyltriphenylene-grafted (14.2%) polysiloxane (DPTP) was successfully synthesized and statically coated on capillary columns as a stationary phase for gas chromatography. The DPTP columns exhibited excellent efficiencies of 3646 plates m(-1) for a 30 m column and 3125 plates m(-1) for a 10 m column, as evidenced by naphthalene measurements at 120 degrees C, which demonstrated the good film-forming ability of DPTP. Thermogravimetric analysis showed that the weight of DPTP is reduced by 2% at 380 degrees C. Separation of the polyethylene pyrolysis product indicated that the maximum allowable operating temperature of the DPTP column is 360 degrees C. The moderate polarity of the DPTP column was investigated in terms of McReynolds constants. The DPTP column was utilized to separate analytes, including aromatic isomers, fatty acid esters, ethers, polycyclic aromatic hydrocarbons and their derivatives, and nitrogenous heterocyclic compounds, on the basis of the column’s strong pi-pi stacking, dipole-induced dipole, and dispersion interactions with solutes. In general, the DPTP column offers great potential as a novel stationary phase for separating various analytes due to its special structure and remarkable separation performance.

The reactivity of azomethines based on trifluoroacetaldehyde hydrate in the Castagnoli-Cushman reaction (CCR) was researched. The impact of the nature of anhydrides explored on the reaction route was determined. The preparative procedures for the synthesis of N-substituted (3R*,4R*)-1-oxo-3-(trifluoromethyl)-1,2,3,4-tetrahydroisoquinoline-4-carboxylic and (1R*,2R*)-4-oxo-2-(trifluoromethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine-1-carboxylic acids in gram scales were elaborated. It was shown that the trifluoromethyl group remarkably decreased the reactivity of azomethines in CCR. The mechanism for the formation of different products depending on the anhydride’s nature was proposed.
