Applications of α-Phosphonovinyl Tosylates in the Synthesis of α-Arylethenylphosphonates via Suzuki-Miyaura Cross-Coupling Reactions

It has been demonstrated for the first time that alpha-phosphonovinyl tosylates could efficiently couple with a range of arylboronic acids to access alpha-arylethenylphosphonates. The unprecedented procedure exhibits excellent functional group tolerance, giving the terminal vinylphosphonates in good to excellent isolated yields (60-99%) under mild reaction conditions.
