A ligand-free Pd-catalyzed hydrophosphorylation of internal alkynes with diphenyl H-phosphonate in various alcohols for the synthesis of E-vinylphosphonates has been reported. This pratical and versatile three-component reaction involves the syn-addition of diphenyl H-phosphonate towards relatively inactive internal alkynes, as well as the concomitant transesterification of diphenyl H-phosphonate. The remarkable features include high stereoselectivity, wide substrate scope and the absence of additional ligands.

Key words: addition reaction, three-component reaction, vinylphosphonate, palladium, internal alkyne
