摘要

烯烃在相当温和的条件下(8.5大气压)转化为醛。在催化量为5% Rh/C和1,3-双(二苯基膦)丙烷(dppp)的存在下(反应物:dppp:Rh/C的比例为250:4:1)，用一氧化碳和甲酸催化合成了CO(105℃)。烯烃RCHCH2对支链醛具有良好的选择性，其中R = Ar, OAc, OCOPh, SPh，而R = SiMe3或SiPh3的线性产物更受青睐。

Use of rhodium on carbon and 1,3-bis(diphenylphosphino)propane to catalyze the regioselective hydroformylation of alkenes with formic acid as the hydrogen source

Alkenes are converted to aldehydes under quite mild conditions (8.5 atm. CO, 105°C) by reaction with carbon monoxide and formic acid in the presence of catalytic amounts of 5% Rh/C and 1,3-bis(diphenylphosphino)propane (dppp) [250:4:1 ratio of reactant:dppp:Rh/C]. Good selectivity for the branched chain aldehydes resulted for the olefins RCHCH₂, where R = Ar, OAc, OCOPh, SPh, while the linear product was favored for R = SiMe₃ or SiPh₃.

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.
