摘要：

Reactions of 4-chloro-5-(p-toluenesul fonylimino)-5H-1,2,3-dithiazole (2) with primary and secondary amines in CH2Cl2 at room temperature gave N'-(p-toluenesulfonyl)-N-alkyl- and N,N-dialkylcyanoformamidines (3) (53-79% yields), respectively. Refluxing of 3 with secondary amines in CH2Cl2 gave 1,3-dialkyl-2-(p-toluenesulfonyl)guanidines (7) (40-99% yields), some of which (7a, 7c) were also directly obtained from the reactions of 2 with the corresponding amines without using the solvent.
