5Asymmetric Hydrogenation of Acetylace Tonates on Raney Nickel Catalyst

E. I. Klabunovskii,N. P. Sokolova,Yu. I. Petrov,V. V. Patrikeev,V. I. Neupokoev,I. A. Rubtsov

Hydrogenation of the acetylacetonates of Ni, Co, Cu, and Zn at atmospheric pressure and at 100 atm both on Ni and on NiM proceeded at a lower rate than the hydrogenation of pure acetylacetone. The rate of hydrogenation grew along the series of acetylacetonates Co < Zn ≤ Ni < Cu (Ni) and Co < Zn ≤ Cu < Ni (NiM).

7Catalytic and Asymmetrizing Activity of Mixed Copper-Nickel Catalysts, Deposited on Aerosil, in the Hydrogenation of Acetylacetone

Yu. V. Vlasenko,E. I. Klabunovskii,A. A. Vedenyapin, L. N. Brezzhunova,I. A. Rubtsov

A mixed Cu-Ni (1∶1) catalyst, deposited on aerosil and modified with D-(+)-tartarie acid, was obtained, which is active in theselective stereoselective hydrogenation of acetylacetone to the (-)-ketol. The optical yield of the ketol is 9.1% at 133°.
