摘要
Oxidative addition of Ph(2)P(O)H to M(PEt(3))(3) (M = Pd, Pt) readily took place at room temperature in benzene to afford cis-MH[P(O)Ph(2)]PPh(2)(OH)](PEt(3)) complexes. The structure of the platinum complex was determined by X-ray crystallography. The palladium complex was found to undergo an insertion reaction with oct-1-yne to give 1- and 2-(diphenylphosphinyl)oct-1-enes. Pd(PPh(3))(4) catalyzed regio- and stereoselective synthesis of alkenyldiphenylphosphine oxides (hydrophosphinylation) from alkynes and Ph(2)P(O)H.
