Abstract
A complex RhH2(Ph2N3) (PPh3)21 has been shown to be an efficient catalyst for the homogeneous hydrogenation of unsaturated compounds (styrene, acrylonitrile, cinnamic acid, cinnamic alcohol and cinnamonitrile) in dimethyl sulfoxide (DMSO) under mild conditions. DMSO appears to play an important role in generating the active catalytic species for hydrogenation of styrene. No catalytic activity for styrene hydrogenation was observed for 1 in solvents such as benzene, toluene, acetone, tetrahydrofuran and N,N-dimethylformamide. The results are discussed in relation to the mechanism of styrene hydrogenation.
期刊介绍：
Journal of Molecular Catalysis (China) is a bimonthly journal, founded in 1987. It is a bimonthly journal, founded in 1987, sponsored by Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, under the supervision of Chinese Academy of Sciences, and published by Science Publishing House, which is a scholarly journal openly circulated both at home and abroad. The journal mainly reports the latest progress and research results on molecular catalysis. It contains academic papers, research briefs, research reports and progress reviews. The content focuses on coordination catalysis, enzyme catalysis, light-ribbed catalysis, stereochemistry in catalysis, catalytic reaction mechanism and kinetics, the study of catalyst surface states and the application of quantum chemistry in catalysis. We also provide contributions on the activation, deactivation and regeneration of homogeneous catalysts, solidified homogeneous catalysts and solidified enzyme catalysts in industrial catalytic processes, as well as on the optimisation and characterisation of catalysts for new catalytic processes.
The main target readers are scientists and postgraduates working in catalysis in research institutes, industrial and mining enterprises, as well as teachers and students of chemistry and chemical engineering departments in colleges and universities. Contributions from related professionals are welcome.
