The operationally simple palladium-catalyzed double-bond migration without heteroatom-containing coordinating functional groups is described. Addition of TaCl5 as a second catalyst greatly enhanced the migration efficiency to provide β-alkylsty

Page column 7, (2008/06/13)
There are provided a process for producing an alkenyl-substituted aromatic hydrocarbon by alkenylation of an alkyl-substituted aromatic hydrocarbon having a hydrogen atom at the α-position of a side chain thereof with a conjugated diene, using a catalyst obtained by the action of an alkali metal compound and an alkali metal or an alkali metal hydroxide on an metal oxide selected from alumina or hydrotalcite by heating in a specific temperature range; and a process for producing an alkenyl-substituted aromatic hydrocarbon, characterized in that the reaction is carried out in the presence of an alkylaminopyridine of formula (1): wherein R1is hydrogen or C1-C6lower alkyl, and R1is C1-C6lower alkyl, using as a catalyst, Na metal, K metal, or an alloy thereof, or a catalyst carrying any of them on an inorganic compound support, or a catalyst obtained by the action of an alkali metal compound and alkali metal or an alkali metal hydride on a metal oxide selected from alumina, alkaline earth metal oxides, hydrotalcite, silica-alumina, or zeolite by heating in a temperature range of 70° C. to 700° C.
