Phosphonium salts and processes for production of and uses for the same

摘要

Novel phosphonium salt of the general formula wherein R<1> and R<2> each is a hydrogen atom or a hydrocarbon group of 1 to 12 carbon atoms which may optionally be substituted; R<3> is a hydrogen atom or a hydrocarbon group of 1 to 5 carbon atoms which may optionally be substituted; R<4>, R<5> and R<6> each is a hydrocarbon group of 1 to 8 carbon atoms which may optionally be substituted; X is a hydroxyl group, a hydroxycarbonyloxy group or a lower alkylcarbonyloxy group, and processes for production of the salts are described. Telomerization catalysts containing said phosphonium salts and processes for production of straight-chain alkadienyl compounds using the same catalysts are also provided.
