Abstract

Supported gold nanoparticles catalyze the oxidation of benzylamines to N-benzylidene benzylamines by molecular oxygen in toluene. The process is general, and para-substituted benzylamines as well as heterocyclic methanamines undergo oxidative condensation. 1- Phenylethanamine and diphenylmethanamine form imines with much less selectivity than benzylamines due to the unfavourable steric hindrance introduced by the substituents at ...
