Pd-catalyzed C-N coupling of vinylbromides and sulfonimidamides : a facile synthesis of N '-vinylsulfonimidamides

• N'-Vinyl sulfonimidamides have been synthesized through a Pd-catalyzed C-N cross coupling between the N'-(imine nitrogen) of N'-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 N'-vinyl sulfonimidamides could undergo hydrogenation with Pd-C/H-2 to provide N'-alkyl sulfonimidamides.
