1,7-Octadiene can be prepared by hydrodimerizing butadiene in the presence of a catalytic amount of palladium, a tertiary phosphine, formic acid a base and optionally a solvent. High selectivities to 1,7-octadiene are obtained if the phosphine has the formula: R1R2R3P wherein R1 is a benzyl group or an optionally unsaturated branched alkyl group having from 3 to 10 carbon atoms with branching occurring at a carbon atom no more than two carbon atoms from the phosphorus atom and R2 and R3 are R1 or independently optionally unsaturated alkyl or aryl groups having from 1 to 10 carbon atoms. |
