The present inventlon is directed to a process for hydrogenating olefinic compounds, in which the hydrogenation is conducted in the presence of a catalyst system comprising (a) a hydride derivative of aluminium having the formule AlH3.xB,AlHY2.xB, AlH2Y.xB,or -(HAlNR)? wherein x is 1, 2 or 3, Y is a halogen atom, n is a number in the range from 4 to 40, R is an aliphatic, cycloaliphatic, or aromatic radical and B is a Lewis base, and (b) a compound of a transition metal. Quantitative yields of hydrogenation can be obtained and the possibility is also afforded of using amines and alcohols as moderators of the olefine hydrogenation in order that selective hydrogenations may be obtained. |
