Reactions of Tp(NH[double bond, length as m-dash]CPh(2))(PPh(3))Ru-Cl with HC[triple bond, length as m-dash]CPh in the presence of H(2)O: insertion/hydration products.
The reaction of benzophenone imine complex (NH[double bond, length as m-dash]CPh(2))[Ru]Cl {[Ru] = Tp(PPh(3))Ru; Tp = HB(pz)(3), pz = pyrazolyl} with HC[triple bond, length as m-dash]CPh in the presence of H(2)O afforded the cis-alkynyl(vinylidene) complex [Ru](C[triple bond, length as m-dash]CPh)([double bond, length as m-dash]C[double bond, length as m-dash]CHPh) , as well as two alkenyl ketone regioisomers [Ru]C(CH(2)Ph)[double bond, length as m-dash]CHC(O)Ph and [Ru]C(Ph)[double bond, length as m-dash]CHC(O)CH(2)Ph . The combination of insertion and hydration process resulted in the unprecedented formation of the alkenyl ketone complexes.
