This reaction is the first example of a palladium-catalyzed addition of aryl halides to vinylic acetates, resulting in aryl ketones. It can be considered as an α-arylation of aldehydes, and thus it is a quite useful synthetic transformation. A broad variety of substituted aryl and heteroaryl bromides can be used, as well as a number of enol acetates. This is a convenient and general method for the preparation of aryl ketones from aldehydes and aryl halides.
