Claims
- 1. A catalyst composition formed from a compound of palladium, the anion of a non-hydrohalogenic acid having a pKa below 2 and a bidentate ligand of phosphorus wherein the divalent group bridging the two phosphorus atoms is 2-hydroxy-2-alkyl-1,3propylene.
- 2. The catalyst composition of claim 1 wherein the bidentate ligand is of the formula ##STR5## wherein R independently is aliphatic or aromatic of up to 10 carbon atoms inclusive and R' is alkyl of up to 6 carbon atoms inclusive.
- 3. The catalyst composition of claim 2 wherein the compound of palladium is a palladium carboxylate.
- 4. The catalyst composition of claim 3 wherein the anion is the anion of trifluoroacetic acid or p-toluenesulfonic acid.
- 5. The catalyst composition of claim 4 wherein R independently is phenyl or substituted aromatic hydrocarbyl having a polar substituent on at least one aromatic ring carbon atoms ortho to the aromatic ring carbon atom through which the R group is attached to the phosphorus.
- 6. The catalyst composition of claim 5 wherein the palladium carboxylate is palladium acetate.
- 7. The catalyst composition of claim 6 wherein R is 2-methoxyphenyl.
- 8. The catalyst composition of claim 6 wherein R is phenyl.
- 9. The catalyst composition of claim 8 wherein the anion is the anion of trifluoroacetic acid.
- 10. The catalyst composition of claim 8 wherein the anion is the anion of p-toluenesulfonic acid.
