Patent ID: 7960565

Claim:
A process for the production of an organometallic compound selected from wherein R 1 , R 2 , R 3 and R 4 each represent hydrogen, R 5 , R 6 , R 7 , R 8 and R 9 are the same or different and each represents hydrogen, a halogen atom, an acyl group having from 1 to about 12 carbon atoms, an alkoxy group having from 1 to about 12 carbon atoms, an alkoxycarbonyl group having from 1 to about 12 carbon atoms, an alkyl group having from 1 to about 12 carbon atoms, an amine group having from 1 to about 12 carbon atoms or a silyl group having from 0 to about 12 carbon atoms; and wherein said organometallic compound is a liquid at 20° C. and atmospheric pressure; which process comprises (i) reacting a ruthenium source compound selected from a substituted or unsubstituted cyclopentadienyl halide ruthenium compound or a substituted or unsubstituted pyrrolyl halide ruthenium compound, with a base material in the presence of a solvent and under reaction conditions sufficient to produce a reaction mixture comprising said organometallic compound, and (ii) separating said organometallic compound from said reaction mixture.
