For several decades, organophosphorus compounds have received attention due to applications in diverse fields such as coordination and materials chemistry, homogeneous catalysis, pharmaceuticals, agrochemicals, additives for polymers, and flame retardants. We were attracted to developing a streamlined method for the synthesis of a myriad of phosphacoumarins and benzophosphacoumarins with the aim of making useful chemical libraries and probes. In addition, the importance of cross-dehydrogenative coupling reactions on Pd-catalyzed direct C-H alkenylation of heteroarenes has been rapidly increased. Herein, we have developed an oxidative alkenylation from the reaction of phosphacoumarins with a wide range of activated as well as non-activated alkenes via aerobic oxidative Heck reactions. Moreover, 3-alkenylphosphacoumarins undergo inverse electron demand Diels-Alder reaction with enamines in situ generated from ketone and pyrrolidine followed by 1, 2-elimination and a dehydrogenation, affording fluorescent benzophosphacoumarins.
