COA of Formula: C9H10O2In 2021 ,《Bio-derived nanosilica-anchored Cu(II)-organoselenium complex as an efficient retrievable catalyst for alcohol oxidation》 was published in Applied Organometallic Chemistry. The article was written by Gogoi, Rajjyoti; Borah, Geetika. The article contains the following contents:
A new copper(II) complex supported onto rice-husk-derived nanosilica was prepared from 2,6-bis((phenylselanyl)methyl)pyridine, salicylaldehyde and copper acetate monohydrate, Cu(OAc)2·H2O. The as-synthesized complex Cu(II)SeNSe@imine-nanoSiO2 (Complex I) was extensively characterized with FT-IR, powder XRD, SEM-EDX, solid-state UV-Vis, ESR, XPS, TGA and BET surface area anal. The catalytic activity of the complex was explored for alc. oxidation reactions using H2O2 as oxidant and acetonitrile as solvent. For comparison, we have also prepared an analogous homogeneous catalyst (Complex II) and characterized it with FT-IR, UV-Vis, LC-MS and ESR analyses. Its catalytic activity was also screened to the same reaction. The immobilized catalyst showed better efficiency with 75%-95% isolated yield compared with the homogeneous one for alc. oxidation with at least five times recyclability without profound loss in activity. In addition to this study using 2-(Benzyloxy)acetaldehyde, there are many other studies that have used 2-(Benzyloxy)acetaldehyde(cas: 60656-87-3COA of Formula: C9H10O2) was used in this study.
2-(Benzyloxy)acetaldehyde(cas: 60656-87-3) is a non-natural aldehyde. It undergoes enantioselective Mukaiyama aldol reaction with silylketene acetal nucleophiles in the presence of C2-symmetric bis(oxazolinyl)pyridine Cu(II) complex (catalyst).COA of Formula: C9H10O2
