A New Oxidative Addition of Ruthenium(0) into an Aryl Halide Bond and Subsequent Intermolecular C-H Insertion.
5289 - 5292.
An unprecedented oxidative insertion of the activated ruthenium complex "Ru(CO)(PPh3)(2)" into aryl halide bonds enables a novel preparation of stable five-coordinate 16-electron d(6) sigma-aryl-Ru(II) complex Ru(CO)(p-C6H4Me)Br(PPh3)(2), which has been characterized by NMR, IR, elemental analysis, and X-ray crystallography. These novel five-coordinate Ru(II) complexes were investigated as potential intermediates in the ortho-arylation of aryl ketones (alpha-tetralone) through C-H activation and resulted in the formation of Ru(CO)(eta(1)-C, kappa(1)-O, alpha-tetralone)X(PPh3)(2) and toluene (X = Br or I).
