SYNTHESIS OF 1,3-DITHIOLIUM SALTS CONTAINING N-METHYLPIPERAZINE

Abstract

The synthesis of 4-aryl-2-(N-methylpiperazin-1-yl)-1,3-dithiol-2-ylium perchlorates has been accomplished by the acid catalyzed heterocyclocondensation of the corresponding substituted phenacyl N-methylpiperazin-1-carbodithioates. The later have been obtained from the reaction of various substituted -bromoacetophenones with a salt of N-methylpiperazine carbodithioic acid. The structures of new synthesized N-methylpiperazine derivatives have been proved by analytical and spectral data.
