And the article contained the following:

Herein, TEMPO (2,2,6,6-tetramethylpiperidine nitroxide) and its derivatives are disclosed as active catalysts for electrophilic halogenation of olefins e.., prop-1-en-1-ylbenzene, alkynes R1CCR2 (R1 = octyl, Ph; R2 = H, Me, n-Bu, Ph), and aromatics R3H (R3 = 3-(carboxymethyl)-4-methoxybenzen-1-yl, 2-[ethoxy(oxo)methane]-1H-indol-3-yl, 5-phenylthiophen-2-yl, etc.). These catalysts are stable, readily available, and reactive enough to activate haleniums including Br+, I+ and even Cl+ reagents. This catalytic system is applicable to various halogenations including haloarylation of olefins or dibromination of alkynes, which were rarely realized in previous Lewis base catalysis or Lewis acid catalysis. The high catalytic ability is attributed to a synergistic activation model of electrophilic halogenating reagents, where the carbonyl group and the halogen atom are both activated by present TEMPO catalysis. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Application In Synthesis of 2-Methoxynaphthalene

On April 30, 2022, Toupalas, Georgios; Morandi, Bill published an article.Recommanded Product: 93-04-9 The title of the article was Non-innocent electrophiles unlock exogenous base-free coupling reactions. And the article contained the following:

Introduced a unifying strategy that eliminates the need for an exogenous base through the use of non-innocent electrophiles (NIE), which were equipped with a masked base that was released in a controlled fashion during the reaction. The universal applicability of this concept were demonstrated by turning multiple, traditionally base-dependent, catalytic reactions into exogenous base-free homogeneous processes. Furthermore, the advantageous features of NIEs were demonstrated in multiple applications, such as in a micromole-scale fluorescence-based assay. This led to the discovery of a Ni-catalyzed deoxygenation reaction of aryl carbamates using isopropanol as a benign reductant. In a broader context, this work provided a conceptual blueprint for the strategic utilization of NIEs in catalysis. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Recommanded Product: 93-04-9

Objectives To determine furfural biotransformation capabilities of Acinetobacter baylyi ADP1 and Acinetobacter schindleri ACE. Results Acinetobacter baylyi ADP1 and A. schindleri ACE could not use furfural as sole carbon source but when acetate was used as substrate, ADP1 and ACE biotransformed 1 g furfural/l in 5 and 9 h, respectively. In both cases, the product of this biotransformation was difurfuryl-ether as shown by FT-IR and H-1 and C-13 NMR spectroscopy. The presence of furfural decreased the specific growth rate in acetate by 27% in ADP1 and 53% in ACE. For both strains, the MIC of furfural was 1.25 g/l. Nonetheless, ADP1 biotransformed 2 g furfural/l at a rate of 1 g/l/h in the stationary phase of growth. A transcriptional analysis of possible dehydrogenases involved in this biotransformation, identified that the areB and frmA genes were highly overexpressed after the exposure of ADP1 to furfural. The products of these genes are a benzyl-alcohol dehydrogenase and an alcohol dehydrogenase. Conclusions Acinetobacter baylyi ADP1 is a candidate for the biological detoxification of furfural, a fermentation inhibitor present in lignocellulosic hydrolysates, with the possible direct involvement of the AreB and FrmA enzymes in the process.

Twist-Bend Nematic Glasses: The Synthesis and Characterisation of Pyrene-based Nonsymmetric Dimers

A selection of pyrene-based liquid crystal dimers have been prepared, containing either methylene-ether or diether linked spacers of varying length and parity. All the diether linked materials, CBOnO.Py (n=5, 6, 11, 12), exhibit conventional nematic and smectic A phases, with the exception of CBO11O.Py which is exclusively nematic. The methylene-ether linked dimer, CBnO.Py, with an even-membered spacer (n=5) was solely nematogenic, but odd-members (n=6, 8, 10) exhibited both nematic and twist-bend nematic phases. Replacement of the cyanobiphenyl fragment by cyanoterphenyl giving CT6O.Py, gave elevated melting and nematic-isotropic transition temperatures, and SmA and SmCA phases were observed on cooling the nematic phase. Intermolecular face-to-face associations of the pyrene moieties drive glass formation, and all these materials have a glass transition temperature at or above room temperature. The stability of the glassy twist-bend nematic phase allowed for its study using AFM, and the helical pitch length, P-TB, was measured as 6.3 and 6.7 nm for CB6O.Py and CB8O.Py, respectively. These values are comparable to the shortest pitch of a twist-bend nematic phase measured to date.
