Metal-free sustainable synthesis of oximes and hydrazones from benzyl alcohol and benzylamine [PDF]

RSC Advances
Herein, we report a one-pot synthesis of oximes and hydrazones via oxidative coupling of alcohols and amines with hydroxylamine hydrochloride and hydrazine, mediated by N-bromosuccinimide (NBS) and phenyliodine(iii) diacetate (PIDA), respectively.
