摘要：

Telomerization of isoprene is characterized by intense thermal effects. The reaction system di-mu-chlorobis(eta3-allyl)-dipalladium(II): tri-n-butylphosphine: sodium methylate: isoprene = 1:2:3:200 in a solvent-mixture of methanol:benzene = 1:3 is used as a model. It is concluded that reaction of the catalyst combined with reduction of Pd(II) is followed by the telomerization reaction. There is a marked influence of Pd and phosphine concentration in the catalyst as well as concentration of isoprene. Results are available to optimize technical applications.
