An efficient iron phthalocyanine catalyzed method was developed for direct oxidative coupling of alcohols with amines to afford corresponding imines. The present protocol is applicable to various substituted aromatic and aliphatic alcohols and amines. The reaction is believed to proceed via activation of alcohols by iron phthalocyanines through Lewis acid–base interaction to form aldehydes, which by nucleophilic attack of amines are converted into the corresponding imines.
