A series of bis(alkylphosphine)trichlorotitanium(III) complexes can be prepared by direct combination of the components in toluene at elevated temperature. The bis(phosphine) complexes are soluble in aromatic hydrocarbon solvents such as benzene and toluene. Molecular weight measurements and epr spectroscopy indicate that the complexes are five-coordinate monomers in benzene. The weakly basic character of the hydrocarbon solvent diminishes...
