Oxidative Addition of Aryl Halides to Cationic Bis(phosphane)rhodium Complexes: Application in C-C Bond Formation

The oxidative addition of chloro-, bromo-and iodobenzene to the cationic bis(phosphane)rhodium complex [Rh(DIPAMP)(MeOH)(2)]BF4 was investigated. The resulting complexes were characterized by X-ray analysis and NMR spectroscopy and applied as catalysts in classical cross-coupling reactions. Product inhibition was observed and quantified by UV/Vis and NMR spectroscopy.
