Abstract

The reaction of benzophenone imine complex (NH [double bond, length as m-dash] CPh₂)[Ru]Cl 1 {[Ru] = Tp(PPh₃)Ru; Tp = HB(pz)₃, pz = pyrazolyl} with HC [triple bond, length as m-dash] CPh in the presence of H₂O afforded the cis-alkynyl(vinylidene) complex [Ru](CCPh)(CCHPh) 3, as well as two alkenyl ketone regioisomers [Ru]C(CH₂Ph)CHC(O)Ph 4 and [Ru]C(Ph) [double bond, length as m-dash] CHC(O)CH₂Ph 5. The combination of insertion and hydration process resulted in the unprecedented formation of the alkenyl ketone complexes.
