Electrochemical C–H/N–H Coupling of Phenothiazines with Halogenated Phenols
摘要
Abstract
A mild and efficient method was proposed for the preparation of N-aryl phenothiazines by C–H/N–H coupling of halogenated phenols with phenothiazines under electrochemical conditions. The reaction proceeded in the absence of a metal catalyst, external oxidants and additives. The desired phenothiazine derivatives were obtained in yields of up to 83%.
