in spite of very different substitution the ynamines 1a-q react with the N-(sulfinyl)arenesulfonamides 2a-c to give the α-sulfonylamidines 4.In on e case we succeeded to isolate both of the configutrtion isomers (E- and Z-4i).The structure of the sulfines 4 is confirmed by spectroscopic data and by some reactions: hydrolysis, photolysis, oxidation, and reaction with 2,3-dimethyl-1,3-butadiene of some sulfines 4 furnish the analogous methylene compounds 5 (exception 6), the 2-oxoamidines 7, and the Diels-Alder adducts 8.
