Bericht: Recent Investigations on Cyclic Sulfur-Nitrogen-Halogen Compounds

Abstract

Cyclic sulfur-nitrogen-halogen compounds constitute a traditional field of inorganic chemistry1-10. Established as long ago as the close of the previous century by DEMARCAY’S preparation of (NSCl)3-, S4N3Cl-, S3N2Cl2-, S3N2Cl-, S3N2Br-compounds11 whose SN cyclic structures were only recognized much later - the study of halocyclothiazenes, as these species are now called, has gained considerable impetus during the past quarter of a century.
