The use of a palladium(II) acetate-organophosphine catalyst system enables an efficient coupling of (1-bromovinyl)phosphonates with aryl boronic acids. A wide range of (1-arylvinyl)phosphonates were prepared in very good yields. The protocol can be effectively scaled up and even allows the use of a (1-chloro­vinyl)phosphonate as the electrophilic coupling partner.
