Palladium-catalyzed phosphorylation of arylsulfonium salts with P(O)H compounds via C-S bond cleavage.

Herein we report a novel palladium-catalyzed phosphorylation of arylsulfonium salts with P(O)H compounds via C-S bond cleavage under mild conditions. The protocol provides a pragmatic strategy applicable to the synthesis of diverse arylphosphonates.
