Catalyst composition and use in preparing polyketones

摘要

Catalyst compositions for preparing polyketones comprising (a) a Group VIII metal compound, containing at least one ligand capable of coordinating to the Group VIII metal, and (b) a boron hydrocarbyl compound are disclosed, in particular catalyst compositions wherein the boron hydrocarbyl compound is a Lewis acid of the formula BXYZ where at least one of X, Y and Z is a monovalent hydrocarbyl group. A preferred catalyst composition comprises a palladium complex and B(C6F5)3.
