ABSTRACT:
This invention relates to the preparation of allyl vinylacetate esters via the catalytic carbonylation of allylic alcohols. The esters are produced in good yield and selectivity using empirically selected 3-component homogeneous palladium dihalide catalysts consisting essentially of 1) palladium(II) halides stabilized with 2) one or more Group VB donor ligands, and 3) in combination with Group IVB metal halide cocatalysts such as tin(II) halides, tin(IV) halides and germanium(II) halides. An improvement in shorter reaction times, increased yields and selectivity over what has been reported in the literature has been found to be attributable to the use of applicant's catalysts rather than the catalysts used in the art.
