The constitution of N-substituted 2-(Iminomethyl)benzenethiols (o-Mercaptobenzaldimines)

Abstract

The constitution of a number of 2-(iminomethyl)benzenethiols and 2- (iminomethyl)-4-nitrobenzene-thiols has been studied by ¹H N.M.R. spectroscopy. A zwitterionic imminium structure is suggested for all the compounds studied except for the 4'-methoxyphenylimine derivative which exists in the thiol form.
