Generation of 1,2-ethanbis(trithiocarbonic acid) dianion from 2,2′-[1,2-ethanediylbis (thio)]bis-1,3-dithiolane and its reaction with alkyl halldes were investigated.
Reaction of trithiocarbonates with meta-chloroperoxybenzoic acid in CH2Cl2 at 0°C affords the corresponding S-oxides. These sulfines are relatively stable compounds which can be purified by chromatography. They react readily with organolithiums in THF at −78°C in a thiophilic manner to give carbanions which are stabilized by three sulfur groups. Hydrolysis affords trithioorthoester oxides. The thermal

A novel method is reported for the synthesis of symmetricdialkyl and cyclic (5, 6 and 7 member) trithiocarbonates from alkyl halides and carbon disulfide in the presence of imidazole and water in DMSO under mild reaction conditions. Imidazole is used as an inexpensive, non-toxic and readily available catalyst in this procedure. GRAPHICAL ABSTRACT
