The reaction of N-vinyl sulfoximines with HPPh 2 , HP(O)Ph 2 , and HP(O)(OMe) 2 gave the corresponding α-( N-sulfoximido) phosphines, phosphine oxides, and phosphonates, respectively, with high regioselectivity in high yield. The N-vinyl sulfoximines showed an enamine-like regioselectivity in hydrophosphination and hydrophosphorylation (Pudovik reaction). While the acid-catalyzed hydrolysis of a cyclic
