The visible-light-induced synthesis of 5-phosphoryl-functionalized pyrroles has been established by eosin Y catalysis, and different electron-donating or electron-withdrawing group substituted secondary Hphosphine oxides and phenacylmalononitriles showed good reactivity toward the reaction, affording the cascade phosphinoylation/cyclization products in 82-98% yields via PÀ C/CÀ N annulation. Step-by-step control experiments and 31 P NMR tracking experiments were further performed to gain the insights of the plausible reaction mechanism and kinetic reaction process. This reaction may have implications for the construction of C(sp 2 )À P bonds in organophosphorus chemistry.
