Abstract:
A process for the selective production of vinyl ester by the reaction of a carboxylic acid with acetylene with a homogeneous catalyst is disclosed and claimed. In a preferred embodiment of this invention, reaction of benzoic acid and acetylene in the presence of Group VIII metal complex catalyst at a temperature of about 50 to 180° C. results in quantitative yields of vinyl benzoate.
