PROBLEM TO BE SOLVED: To provide a general synthesis method capable of providing various alkenyl phosphorus compound and a derivative thereof using a raw material which is easily available and easily handled without using a catalyst. SOLUTION: An alkenyl
Copper (II)-catalyzed regio- and stereoselective addition of H/P(O)R 2 to alkynes

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 alkynes and to the nature of different substituents in the H-P(O)-compounds.
Epoxysilanes as substrates in regio- and stereo-specific synthesis of silylated γ-hydroxyphosphane oxides, precursors of stereodefined allylphosphane oxides
González-Nogal, Ana M.,Cuadrado, Purificación
, p. 8080 - 8087 (2013/08/23)
Epoxysilanes experienced trans stereospecific α- or β-cleavage by the lithium derivative of methyldiphenylphosphane oxide leading to different compounds. The behaviour of the epoxysilanes towards this nucleophilic reagent depends on the nature of the sily
