title: Alkenylation of phosphacoumarins via aerobic oxidative Heck reactions and their synthetic application to fluorescent benzophosphacoumarins.
abstract: Alkenylation of phosphacoumarins is developed from the reaction of phosphacoumarins with a variety of activated as well as nonactivated alkenes via aerobic oxidative Heck reactions. In addition, 3-alkenylphosphacoumarins undergo an inverse electron demand Diels-Alder reaction (IEDDA) with enamines in situ generated from ketone and pyrrolidine followed by 1,2-elimination and a dehydrogenation, producing fluorescent benzophosphacoumarins.
