    摘要： A catalytic composition effective in the selective hydrogenation of olefinic double bonds, comprising the reaction product between: (A) at least one complex of a transition metal having the following general formula (I): M(R1)(R2)(R3)(R4)  (I)  wherein: M is selected from titanium and zirconium, preferably titanium; each of the radicals R1, R2, R3 or R4, independently, represents an organic or inorganic group of an anionic nature &sgr;-bound to M, on the condition that at least one, and preferablyat at least two, of these radicals is an organic group; and (B) at least one organometallic compound of magnesium having the following formula (II): Mg(R5)n(R6)(2−n)  (II)  wherein: R5 or R6 each independently represent an aliphatic or aromatic hydrocarbon group having from 1 to 20 carbon atoms, and “n” is a decimal number between 0 and 2.0. Said catalytic composition advantageously and selectively promotes the direct hydrogenation of double bonds of an olefinic type, with high rates and with a reduced formation of isomers.
