摘要： Palladium complexes having the general formula Pd(R'CO.sub.2).sub.2 X where R' is C.sub.1 to C.sub.10 alkyl or C.sub.6 to C.sub.10 aryl and X is a chelating ligand of formula (R.sup.2).sub.2 PYP(R.sup.2).sub.2 where the R.sup.2 groups are independently selected from C.sub.1 to C.sub.4 alkyl, phenyl or alkoxy substituted phenyl, and Y is --(CH.sub.2).sub.n -- where n=2 to 4 are provided. The complexes may be prepared by reacting the compounds Pd(R'CO.sub.2).sub.2 and (R.sup.2).sub.2 PYP(R.sup.2).sub.2 together in an aromatic solvent at a temperature of less than 60.degree. C. in amounts such that the molar ratio of the two compounds is in the range 1.2:1 to 1:1.2.

摘要： A process for preparing terpolymer polyketones comprises reacting at least two olefins with carbon monoxide at elevated temperature and pressure in the presence of a catalyst prepared from (a) a source of palladium, (b) a source of an anion which either does not coordinate with palladium or is less strongly coordinating to palladium than both carbon monoxide and the olefin(s) used and (c) a bisphosphine of formula (R.sup.1).sub.2 P--R--P(R.sup.1).sub.2 wherein R.sup.1 is an optionally polar substituted aromatic hydrocarbyl group and R is a divalent organic bridging group of formula --(CH.sub.2).sub.n --where n=2 to 8 and (d) a 1,4 quinone. The process is characterized by being carried out in a solvent comprising a mixture of an aprotic polar solvent and from 0.0001 to 0.5% by weight water. The particular solvent system used is especially useful for preparing terpolymer polyketones of high molecular weight.
