Abstract

The reaction of α-alkynyl ketones with o-phenylenedithiol, which leads to the formation of 2-acylmethylbenzo-1,3-dithioles, was investigated. Reactions of the latter with hydrazine hydrate and hydroxylamine and oxidation were realized. Difficult-to-obtain 2-acylmethylenebenzo-1,3-dithioles were obtained by the reaction of α-bromoalkynyl ketones with o-phenylenedithiol. The IR and PMR spectra of the synthesized compounds are presented.
