The in situ generation of thiazyl trichloride: a synthon for C–N–S heterocycles
Abstract
The novel reagent NSCl3 is readily generated by treatment of (NSCl)3 with an excess of SO2Cl2; the reactions of NSCl3 with methacrylonitirle or thioacetamide produce 4-cyanosiothiazole or 5-methyl-1,3,2,4-dithiazolium chloride, respectively, in good yields.
