Reusable Copper-Aluminum Hydrotalcite/rac-BINOL System for Room Temperature Selective Aerobic Oxidation of Alcohols

An efficient catalyst system consisting of copper‐aluminum hydrotalcite/rac‐BINOL ligand has been developed for the oxidation of alcohols using air as a green oxidant at room temperature. Various alcohols could be transformed into their corresponding aldehydes or ketones in good to excellent yields using the set of optimal conditions. This composite catalytic system can also be recovered and reused for several cycles without a significant loss of catalytic activity.
