Solvent-Free Oxidation of Benzyl Alcohol by 30% H2O2 over LDH Hosted Chromium Complex
A Mg–Al layered-double hydroxide (LDH) intercalated by sulphonato-salhen-chromium (III) complex was prepared and then used to the selective oxidation of benzyl alcohol by 30% H2O2. without any organic solvent, phase transfer catalyst or additive. The results revealed that the LDH hosted chromium complex exhibited much higher catalytic performance than its homogeneous analogue. Under the optimal reaction conditions, the highest conversion of benzyl alcohol reached 52.1%, with 100% of the selectivity to benzyldehyde.
