Methyl Pyridine

Oxidation with or without subsequent methylation of the pyridine of 2,6-bis(diphenylphosphine)methyl pyridine affords di- and tricationic phosphonium salts. These species are used as Lewis acid catalysts for the dimerization of 1,1-diphenylethylene, the hydrodefluorination of 1-fluoroadamantane, and the dehydrocoupling of phenol and silane.
