摘要

Abstract The reaction of carbon disulfide with alkaline metal in dimethyl formamide yields 1, 3-dithiole-2-thione-4, 5-dithiolate 1 and trithiocarbonate in equimolar amounts. 1 in dimethyl formamide solution isomerizes to 1, 2-dithiole-3-thione-4, 5-dithiolate 3 at 120–140° C in 1– 2 h quantitatively, 3 was isolated as zinc complex by addition of ZnCl2 and NEt4Br. The resulting zinc complex enables the preparation of 4, 5-bis (ben-zoylthio)-1, 2-dithiole-3- ...
