Preparation of optionally substituted 1,7-diolefin (I) comprises hydrodimerization of non-cyclic olefins with at least two conjugated double bonds in the presence of a reducing agent and a catalyst such as carbene metal complex, where: the metal is from VIII-X group. Preparation of optionally substituted 1,7-diolefin (I) comprises hydrodimerization of non-cyclic olefins with at least two conjugated double bonds in the presence of a reducing agent and a catalyst such as carbene metal complex, where: the metal is from VIII-X group; and the carbene ligand is of formula (a)-(d). R 1, R 2 : -(CH2)n-B 1; B 1 : 6-14C mono- or polycyclic aryl, 5-14C mono- or polycyclic heterocyclic or heteroatom (where the heterocycle is optionally substituted with 1-3 heteroatoms of N, O or S); n : 0-4; and R 3-R 6 : H (preferred), alkyl-, (hetero)aryl-, -CN, -COOH, -COO-alkyl-, -COO-aryl-, -OCO-alkyl-, OCO-aryl-, -OCOO-alkyl-, OCOO-aryl-, -CHO, -CO-alkyl-, CO-aryl-, NH 2, -NH(alkyl)-, -N(alkyl) 2-, NH(aryl)-, F, -Cl, -Br, -I, -OH, -CF 3, -NO 2, -ferrocenyl, -SO 3H or -PO 3H 2 (all optionally substituted), where the alkyl group contains 1-12 carbon atoms and aryl group contains 5-14 carbon atoms. Where R 3, R 4 exhibits a partially bridged aliphatic or aromatic ring. [Image]. |
