Abstract

The reaction of N,N′-bis(dithiocarboxy)piperazine with acetylenic ketones and methyl propiolate gave N,N′-bis(acylvinyldithiocarbo)- and N,N′ -bis(methoxy-carbonylvinyldithiocarbo)piperazines. Heating the compounds obtained with perchloric acid leads to intramolecular cyclization with the formation of N,N′ -bis[2-acyl(methoxycarbonyl)methyl-1,3-dithietanium]piperazine perchlorates.
