Claims
- 1. A telomerization catalyst comprising a phosphonium salt of the general formula ##STR27## wherein R.sup.1 and R.sup.2 each is a hydrogen atom or a hydrocarbon group of 1 to 12 carbon atoms which may optionally be substituted; R.sup.3 is a hydrogen atom or a hydrocarbon group of 1 to 5 carbon atoms which may optionally be substituted; R.sup.4, R.sup.5 and R.sup.6 each is a hydrocarbon group of 1 to 8 carbon atoms which may optionally be substituted, at least one of R.sup.4, R.sup.5 and R.sup.6 being an aryl group; X is a hydroxyl group, a hydroxycarbonyloxy group or a lower alkylcarbonyloxy group, the substituents of the substituted hydrocarbon group being di(lower alkyl) amino, cyano, --SO.sub.3 M or --COOM, wherein M is an alkali metal, and a palladium compound.
- 2. The catalyst claimed in claim 1 wherein R.sup.1 and R.sup.2 in general formula (I) each is a hydrogen atom or an aliphatic hydrocarbon group of 1 to 12 carbon atoms and R.sup.3 is a hydrogen atom or an aliphatic hydrocarbon group of 1 to 5 carbon atoms.
- 3. The catalyst claimed in claim 1 wherein R.sup.4, R.sup.5 and R.sup.6 in general formula (I) each is an aryl group of 6 to 8 carbon atoms which may optionally be substituted by a group of the formula --SO.sub.3 M (where M is an alkali metal atom).
- 4. The catalyst claimed in claim 1 wherein the proportion of the phosphonium salt is at least 6 moles per gram-atom of palladium in the palladium compound.
- 5. The catalyst claimed in claim 4 wherein the proportion of the phosphonium salt is in the range of 10 to 200 moles per gram-atom of palladium in the palladium compound.
