Abstract

Diruthenium complexes have been shown to effectively catalyze the cleavage of carbon-hydrogen bonds in benzene and pyridine to form carbon-silicon bonds. However, the catalytic cycle of these diruthenium complexes is still unknown. Two stable dimethyl diruthenium complexes were synthesized using CH3MgBr and CH3I with yields between 57-68% and protonated with Brookhart's acid and triflic acid. Protonation of the dimethyl diruthenium complexes resulted in promising reactive monomethyl diruthenium complexes, which have been tested as possible intermediates in the catalytic cycle.
