Catalysis of the transfer of hydrogen from 2-propanol to cyclohexanone by immobilized ruthenium tetrasulfate

Abstract

Heterogenized metal complex systems prepared by immobilization of ruthenium tetrasulfate on the surface of silica gel containing γ-aminopropyl groups or on the surface of modified styrene-divinylbenzene copolymer catalyze the transfer of hydrogen from 2-propanol to cyclohexanone in both Ar and air. It has been shown that the activity and stability of the obtained catalysts depend on the concentration of the promoting alkali and on the nature of the support.
