Synthese von 5‐Hetaryl‐1,3‐dithiol‐Derivaten durch Reaktion von Hetarylmethyl‐dithiokohlensäurediestern mit Schwefelkohlenstoff

Abstract

Synthesis of 5‐Hetaryl‐1,3‐dithiole Derivatives by Reaction of Hetarylmethyl‐dithiocarbonates with Carbon Disulfide (Pyrid‐2‐yl)‐ and (quinol‐2‐yl)‐dithiocarbonates 4 and 7 cyclocondense with carbon disulfide to yield 4,5‐disubstituted 1,3‐dithiole‐2‐thiones 5 and 8a – d after alkylation reaction. 8 is transformed into the 2‐oxo‐derivatives 9 by reaction with mercuric acetate. A series of heterocyclic substituted dithiocarbonates 10a , 10b , 12a , 12b , and dithiocarbamates 12c – g , respectively, is synthesized by reactions of halomethylheterocycles with the corresponding salts of xanthates or dithiocarbamates.
