| titleOfInvention | A kind of method that catalytic hydrogenation carboxylate reduction prepares alcohol |
| abstract | The invention discloses one kind with 2（Diphenyl phosphine ethyl）‑（5,6,7,8 tetrahydric quinoline groups）Catalyzed by ruthenium complexes agent of the amine for ligand, the method that alcohol is prepared to carboxylic acid ester compound hydro-reduction.Catalyst para Toluic Acid Arrcostab, aromatic ester, fatty ester etc. have efficient catalytic activity.The preparation method of the present invention is simple, and stability is good, and catalyst activity is high, and dosage is only the 0.025% ~ 0.005% of substrate mole.For the production of alcohols, method is simple, environmental pollution is small, high income, at low cost.Use formula（1）Complex, using sodium borohydride as additive, successfully by most of carboxylate hydrogenating reduction into alcohol, and turn over number TON can reach 50000, particularly to the aromatic ester for carrying electron-withdrawing substituent, the alcohols alkali that most of catalyst uses is replaced with co-catalyst sodium borohydride so that cost reduction, it is easy to operate, it is easy to industrialized production. |
