                                    A novel synthesis of N-sulfonylamidines by catalyst-free hydroamination of N, N-disulfonyl ynamides with amines was developed. Alkyl amines react with N, N-disulfonyl ynamides under mild conditions, whereas aryl amines require higher temperatures. Plausible mechanisms are proposed to explain this reaction.
