Abstract

The preparation of S-vinyl and S-(2-substituted) ethenyl derivatives of sulfoximines is described. Vinyl-,(2-phenylethenyl)-,(2, 2-diphenylethenyl)-,(2-methyl-l-propenyl)-,[2-@- toly1) ethenyll-, and [2-(2-furanyl)-ethenyl](dimethy1amino) phenyloxosulfonium fluoborates were found to undergo an addition-elimination reaction sequence with protic nitrogen and carbon nucleophiles, resulting in ethylenation of the nucleophile and N, N- ...
