Abstract
This invention is a process for the production of acetylated aromatic products, including acetyl benzoeyclobutenes, in one step and in high yield. The process comprises contacting an aryl halide with an alkyl vinyl ether in the presence of a zerovalent palladium catalyst complex and a hydrogen halide acceptor in a aqueous solvent mixture containing at least about one molar equivalent of water based on moles of the aryl halide.
