Abstract

Reported herein is the gold-catalyzed alkenylation and arylation of phosphorothioates using alkenyl and aryl iodides. The facile transmetalation between Ag-sulfur complex and Au(III) intermediate formed after oxidative addition is the key to the success of this transformation. This methodology operates under mild reaction conditions with catalyst loading as low as 1 mol%, thereby providing an efficient access to biologically active S-alkenyl and S-aryl phosphorothioates
