Cu( i )/Fe( iii )-Catalyzed C–P cross-coupling of styrenes with H-phosphine oxides: a facile and selective synthesis of alkenylphosphine oxides and β-ketophosphonates

Cu(i)/Fe(iii)-Catalyzed phosphorylation and oxyphosphorylation of styrenes with H-phosphonates which can be controlled by varying the reaction temperature are developed. This study offers a new and expedient strategy for the synthesis of useful alkenylphosphine oxides and β-ketophosphonates in satisfactory yields. Moreover, the transformation is proposed to proceed via a radical process and exhibits a broad substrate scope and good functional group tolerance.
