The catalytic P-H bond addition to enynes showed selective reactions, which involved the triple bond only. The presence of two triple bonds in diynes resulted in bis-hydrophosphorylation product under these conditions (Scheme 8.3). [Pg.215]

The first aza-Perkov reaction between N-sulfonyltrichloroacetimidoyl-phosphonates (450) and hydrophosphoryl nucleophilic reagents led to C,N-diphosphorylated dichlorovinylsulfonamides (452). Intermediacy of the bis-phosphonates (451) in this transformation has been unequivocally corroborated (Scheme 105). ... [Pg.370]
