Abstract
A method has been developed for the synthesis of N- and S-vinyl derivatives of heteroaromatic compounds from NH heterocycles or their thiols in the phase-transfer catalytic system ClCH2CH2Br-KOH (s)-18-crown-6-toluene. It is shown that it is possible to prepare N,S-divinyl derivatives of 3-mercaptoindole and 2-mercaptobenzimidazole.
