Dithietanes

Cefotetan is an injectable antibiotic of the cephamycin type for prophylaxis and treatment of bacterial infections. It is often grouped together with second-generation cephalosporins and has a similar antibacterial spectrum, but with additional anti-anaerobe coverage.

1,3-Dithietane is a dithietane. It is a colorless, crystalline, unpleasant-smelling solid. It was first prepared in 1976 by the reaction of bis(chloromethyl) sulfoxide with sodium sulfide to give 1,3-dithietane 1-oxide, followed by THF-borane reduction.

1,2-Dithietane is a dithietane. It is a heterocyclic compound with a four-membered ring. Two sulfur atoms are adjacent, and the molecule is saturated. 1,2-Dithietane has not been produced as of 2000. The combination of ring strain, and lone pairs of electrons, which repel each other, on the sulfur atoms makes the sulfur-sulfur bond too weak to produce the molecule. However a few derivatives are known. 3,4-Diethyl-1,2-dithietane 1,1-dioxide has one sulfur fully oxidised. Dithiatopazine is a tricyclic compound with the -S-S- as a bridge. 1,2-Dithietan-3-one, the ketone of 1,2-dithietane, was pro
