  Syntheses of new diphenylphosphinoacetatorhodium(I) complexes and their catalytic reactivities in hydrogenation of aromatic compounds

  摘要：

  The diphenylphosphinoacetic acid Ph2PCH2COOH was readily converted to its silver salt [Ag(Ph2PCH2COO)] (1), and subsequent reactions of 1 with [Rh(cod)Cl]2 (cod = 1,5-cyclooctadiene) and [Rh(CO)2Cl]2 gave [Rh(cod)(Ph2PCH2COO)] (2) and [Rh(CO)2(Ph2PCHCOO)] (3), respectively. Spectroscopic data and some physical properties of these new compounds are described. The complexes 2 and 3 at 50-degrees-C showed catalytic hydrogenation activities towards benzene and a variety of substituted benzenes. The turn-over number (TN) for the arene hydrogenations with 2 under 5 kg/cm2 of H-2, decreased with the following sequence: benzene > toluene > anisole > ethylbenzene > p- and m-xylenes > methyl benzoate. Benzonitrile and nitrobenzene did not yield any products with hydrogenated benzene-ring moieties, and the latter substrate gave only aniline. The activity sequence observed for the arene hydrogenation resulted from steric and electron-withdrawing effects of the substituents of the benzene rings. In benzene hydrogenation with 2 under 50 kg/cm2 of H-2 at 50-degrees-C for 36 h, the TN value was found to be about 5800. Complex 2 also showed similar hydrogenation activities towards 1,2,3,4-tetrahydronaphthalene and furan.
