摘要：

Palladium (II) compounds (palladium dichloride, acetate and acetylacetonate) in conjunction with triphenylphosphine disserved in 1-butyl-methyl imidazolium tetrafluoroborate, hexafluorophosphate or trifluoromethanesulfonate are able to dimerize butadiene into 1,3,6-octatriene in a typical two-phase catalytic reaction with 100% selectivity. The reaction product is easily separated from the reaction mixture by simple decantation, and the recovered ionic liquid catalyst solution can be reused several times without significant changes in catalytic activity or selectivity.
