ChemInform Abstract: Reaction of Cyanoformamidines with 2,2,4,4‐Tetrakis(trifluoromethyl)‐1,3‐dithietane.

The reaction of the cyanoformamidine (III), generated in situ from cyanogen (I) and dimethylamine (II), with the dimer (IV) of hexafluorothioacetone yields a separable mixture of the thiazolines (V) and (VI).
