A novel and efficientmethod for the synthesis of aryl phosphonates fromarylhalides and trialkylphosphites via EDA complex-based photochemistry has been developed. It is demonstrated that aryl radicals, generated from the photoexcitation of the EDA complex formed by arylhalide and potassium thioacetate, could be intercepted with trialkylphosphite to produce the corresponding aryl phosphonates in
