Phosphonium salts, processes for production thereof and a telomerization catalyst comprising the same, and phosphines deriving the same and processes for production of the phosphines

摘要

Phosphonium salts (I) are new. Phosphonium salts of formula (I) are new. [Image] R1>, R2>phenyl optionally substituted by lower alkyl; R3>phenylene optionally substituted by lower alkyl; R7>, R8>H or 1-12C optionally substituted hydrocarbyl, and R9>H or 1-5C optionally substituted hydrocarbyl. Independent claims are included for the following: (1) preparation of (I); (2) a telomerization catalyst which comprises (I) and a palladium compound, but comprising no alkali metal compound; (3) production of an alkadienyl compound which comprises reacting a conjugated diene with an active hydrogen compound in the presence of the telomerization catalyst; (4) new amine salts of sulfonated phosphine compounds of formula (III), and (5) preparation of (III).
