The novel reagent NSCI3 is readily generated by treatment of (NSC1)3 with an excess of S02C12; the reactions of NSCI3 with methacrylonitrile or thioacetamide produce 4-cyanoisothiazole or 5-methyl-l,3,2,4-dithiazolium chloride, respectively, in good yields. ... Although NSF3 is well characterized,' the corresponding chloride, NSCl3, is unknown. We describe here the generation and 14N nmr spectroscopic characterization of this therm- ally unstable compound and its ...
