COMPETITIVE HYDROGENATIONS OVER A RUTHENIUM CATALYST

Hydrogenations of three individual substrates (alpha-methylstyrene, be nzaldehyde, cyclohexanone) were carried out on a ruthenium catalyst. O n the basis of these results, selectivities of competitive hydrogenati ons of alpha-methylstyrene-benzaldehyde, benzaldehyde-cyclohexanone an d alpha-methylstyrene-cyclohexanone binary mixtures were evaluated. It was shown that the reactivity of individual substrates could be subst antially different when hydrogenated competitively with another compou nd in a binary system.
