Patent ID: 7541506

Claim:
A process for the catalytic telomerization of an acyclic olefin having at least two conjugated double bonds (I) comprising: removing alkynes and 1,2-butadiene, if present, from a mixture of 1,3-butadiene with other C 3 -, C 4 - and/or C 5 -hydrocarbons; and then telomerizing said treated mixture of 1,3-butadiene with other C 3 -, C 4 - and/or C 5 -hydrocarbons, as said acyclic olefin having at least two conjugated double bonds, with at least one nucleophile, and one or more complexes comprising one or more metals of groups 8 to 10 of the Periodic Table of the Elements and at least one carbene ligand having one of the following formulae where R X1 , R X2 , R X3 , R X4 , R X5 , R X6 : are each H R 2 ; R 3 : are identical or different and are each a) a linear, branched, substituted or unsubstituted cyclic or alicyclic alkyl group having from 1 to 24 carbon atoms, or b) a substituted or unsubstituted, monocyclic or polycyclic aryl group having from 6 to 24 carbon atoms or c) a monocyclic or polycyclic, substituted or unsubstituted heterocycle having from 4 to 24 carbon atoms and at least one heteroatom selected from the group consisting of N, O, and S, R 4 , R 5 , R 6 , R 7 , are identical or different and are each hydrogen, alkyl, aryl, heteroaryl, —CN, —COOH, —COO-alkyl, —COO-aryl, —OCO-alkyl, —OCO-aryl, —OCOO-alkyl, —OCOO-aryl, —CHO, —CO-alkyl, —CO-aryl, —O-alkyl, —O-aryl, —NH 2 , —NH(alkyl), —N(alkyl) 2 , —NH(aryl), —N(alkyl) 2 , —F, —Cl, —Br, —I, —OH, —CF 3 , —NO 2 , -ferrocenyl, —SO 3 H, —PO 3 H 2 , where the alkyl groups have 1-24 carbon atoms and the aryl groups have from 5 to 24 carbon atoms and the radicals R 4 and R 5 optionally are part of a bridging aliphatic or aromatic ring, wherein, when the catalytically active metal of groups 8 to 10 of the Periodic Table is Pd, substituents R 2 and/or R 3 are as defined in subgroup (c) above.
