Abstract:
N0-Vinyl sulfonimidamides have been synthesized through a Pd-catalyzed C–N cross coupling between the N0-(imine nitrogen) of N0-deprotected sulfonimidamides and vinyl bromides. The hitherto unreported products were obtained in moderate to excellent yield, and the C–C double bond geometry of the vinylic substrates were retained during the course of reaction. Single crystal X-ray crystallographic analysis confirmed the product structure. Furthermore, we demonstrate that the formed N0-vinyl
sulfonimidamides could undergo hydrogenation with Pd–C/H2 to provide N0-alkyl sulfonimidamides
