摘要

Abstract Cu (acac) 2 is the new universal catalyst for β-E regio-and stereoselective syn- addition of the H–P (O)-bond of diphenylphosphine oxide, H-phosphinates, dialkylphosphites to various alkynes in the synthesis of P (O)-containing alkenes. Without additives and ligands Cu (II)-compounds showed better results than CuI or Ni (acac) 2. The catalytic system developed is tolerant to typical organic functional groups present in the ...
