The article was titled 《A green approach for aerobic oxidation of benzylic alcohols catalysed by CuI-Y zeolite/TEMPO in ethanol without additional additives》, and you may find the article in New Journal of Chemistry.Computed Properties of C7H7BrO The information in the text is summarized as follows:
An efficient and green protocol for aerobic oxidation of benzylic alcs. in ethanol using CuI-Y zeolite catalysts assisted by TEMPO (TEMPO = 2,2,6,6-tetramethyl-1-piperidine-N-oxyl) as the radical co-catalyst in the presence of atm. air under mild conditions is reported. The CuI-Y zeolite prepared via ion exchange between CuCl and HY zeolite was fully characterized by a variety of spectroscopic techniques including XRD, XPS, SEM, EDX and HRTEM. The incorporation of Cu(I) into the 3D-framework of the zeolite rendered the catalyst with good durability. The results of repetitive runs revealed that in the first three runs, there was hardly a decline in activity and a more substantial decrease in yield was observed afterwards, while the selectivity remained almost unchanged. The loss in activity was attributed to both the formation of CuO and the bleaching of copper into the liquid phase during the catalysis, of which the formation of CuO was believed to be the major contributor since the bleaching loss for each run was negligible (<2%). In this catalytic system, except TEMPO, no other additives were needed, either a base or a ligand, which was essential in some reported catalytic systems for the oxidation of alcs. The aerobic oxidation proceeded under mild conditions (60°C, and 18 h) to quant. and selectively convert a wide range of benzylic alcs. to corresponding aldehydes, which shows great potential in developing green and environmentally benign catalysts for aerobic oxidation of alcs. The system demonstrated excellent tolerance against electron-withdrawing groups on the Ph ring of the alcs. and showed sensitivity to steric hindrance of the substrates, which is due to the confinement of the pores of the zeolite in which the oxidation occurred. Based on the mechanism reported in the literature for homogenous oxidation, a mechanism was analogously proposed for the aerobic oxidation of benzylic alcs. catalyzed by this Cu(I)-containing zeolite catalyst. The experimental part of the paper was very detailed, including the reaction process of (4-Bromophenyl)methanol(cas: 873-75-6Computed Properties of C7H7BrO)
