process for the production of deep internal olefins, in primary alkylaluminiumverbindungen by isomerisation - displacement

摘要

A deep olefin internal olefin is reacted with a C3-4 primary alkyl aluminum chloride in the liquid phase in the presence of a catalyst system formed from (i) a dicyclopentadienyl dihalide or halohydride of zirconium or hafnium and (ii) a hydridic co-catalyst component. Unlike prior art procedures, negligible quantities of by-product paraffins are formed in the process.
