The present invention provides a process for preparing a vinylaromatic compound comprising reacting an arylmetal reagent selected from arylmagnesium reagents and aryllithium reagents with a vinylphosphate in the presence of a palladium catalyst. The present invention also provides a process for preparing a vinylphosphate comprising reacting an enolizable ketone with a sterically hindered Grignard reagent and a halophosphate diester.
