Preparation, Characterization, and X-ray Structure of the 1:1 Complex of o-Acetylstyrene and Carbonylbis(triphenylphosphine)ruthenium. A New Catalyst for the Copolymerization of Acetophenone and 1,3-Divinyltetramethyldisiloxane
摘要:
Treatment of dihydridocarbonyltris(triphenylphosphine)ruthenium with a stoichiometric amount of styrene, followed by addition of o-acetylstyrene leads to a 1:1 complex of o-acetylstyrene and carbonylbis(triphenylphosphine)ruthenium. This species has been fully characterized and its structure determined by X-ray crystallography. This 1:1 complex is able to-catalyze the copolymerization of acetophenone and 1,3-divinyltetramethyldisiloxane.
