CATALYTIC COMPOSITION FOR HYDROGENATION OF OLEFINICALLY UNSATURATED COMPOUNDS, METHOD OF PREPARATION THEREOF, AND METHOD OF HYDROGENATION OF OLEFINICALLY UNSATURATED COMPOUNDS Russian patent published in 2001 - IPC

FIELD: organic synthesis. SUBSTANCE: catalytic composition for selective hydrogenation olefinic double bonds contains reaction product of (i) at least one monocyclopentadienyl complex of transition metal having general formula (R)M(R¹)(R²)(R³), wherein M is selected from titanium, zirconium, and hafnium; R is anion including η⁵- cyclopentadienyl ring coordinated to M; R¹,R², and R³ are organic or inorganic anionic-nature groups linked to M through σ-bonds and (ii) at least one organomagnesium compound having general formula Mq(R⁴)_n(R⁵)_(2-n), wherein R⁴ and R⁵ are linear aliphatic groups with 1 to 20 carbon atoms and n is decimal number between 0.5 and 2.0. Method of preparing such composition and hydrogenation method are also described. EFFECT: increased composition activity and simplified hydrogenation process. 25 cl, 2 tbl, 13 ex
