The organorhodium(I) complexes [Rh(PNP)R] [PNP = 2,6-bis(diphenylphosphanylmethyl)pyridine, R = CH3 (3a), C6H5 (3b)] were synthesized from [Rh(PNP)(C2H4)IBF4 (1a) and LiR and characterized by 31P-, 1H-, and 13C-NMR spectroscopy and EI mass spectrometry. In a THF solution saturated with ethylene 3a and 3b form the five-coordinate ethylene organorhodium(I) complexes [Rh(PNP)R(C2H4)] (5a, b). The stable monohydridorhodium(III) complex [Rh(PNP)ClH-(CH3CN)]SO3CF3 (7) was obtained by the reaction of [Rh(PNP)Cl] with HSO3CF3 in a solution of THF/acetonitrile and characterized by X-ray crystallography. In a THF solution the organorhodium(I) complexes 3a, b react upon the addition of either HSO3CF3 or HNMe3Cl with the immediate release of the respective hydrocarbon HR.
