Synthesis and characterization of organorhodium(I) complexes with the tridentate ligand 2,6-bis(diphenylphosphanylmethyl)pyridine [Rh(PNP)R] (R = CH3, C6H5) and their reactivity toward ethylene and protic acids

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.

On the Coordination of Olefins and Secondary Amines at the Cationic [2,6-Bis(diphenyIphosphanylmethyl)pyridine]rhodium(I) Fragment [Rh(PNP)]+ - Synthesis and Characterization of [Rh(PNP)(L)]X (L = Ethylene, Styrene, HNR2; X = BF4, PF6, CF3so3)

The cationic rhodium(I) complexes [Rh(PNP)(C2H4)]X; X = BF4 (1a), PF6 (1b), CF3SO3 (1e) were prepared by addition of the tridentate ligand 2,6-bis(diphenylphosphanylmethyl)pyridine (PNP) to a solution of [Rh(C2H4)2(solv)2]X (solv = acetone or THF) under ethylene. The complexes were characterized by IR and 1H-, 13C-, and 31P-NMR spectroscopy. The coordination of two ethylene molecules at the [Rh(PNP)]+ fragment could be detected by dynamic proton resonance of a solution of la under free ethylene. The styrene complex [Rh(PNP)(styrene)]BF4 (4) was obtained by substitution of the ethylene from la with an excess of styrene. The π coordination of C2H4 and styrene in la and 4 respectively was confirmed by X-ray crystal structure analysis. The olefin complexes react with an excess of the secondary amine to give the corresponding amine complexes [Rh(PNP)(HNR2)]X; HNR2 = piperidine (5), HNMe2 (6), HNEt2 (7). Conversly, the amine could be released from the amine complexes with an excess of ethylene at low temperature by the formation of the ethylene complex 1. VCH Verlagsgesellschaft mbH,.
