摘要
The reaction of benzophenone imine complex (NHCPh 2 )[Ru]Cl 1 {[Ru] = Tp(PPh 3 )Ru; Tp = HB(pz) 3 , pz = pyrazolyl} with HCCPh in the presence of H 2 O afforded the cis-alkynyl(vinylidene) complex [Ru](CCPh)(CCHPh) 3, as well as two alkenyl ketone regioisomers [Ru]C(CH 2 Ph)CHC(O)Ph 4 and [Ru]C(Ph)CHC(O)CH 2 Ph 5. The combination of insertion and hydration process resulted in the unprecedented formation of the alkenyl ketone complexes. © 2009 The Royal Society of Chemistry.
