Abstract

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 H-phosphine oxides and phenacylmalononitriles showed good reactivity toward the reaction, affording the cascade phosphinoylation/cyclization products in 82–98% yields via P−C/C−N annulation. Step-by-step control experiments and 31P 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(sp2)−P bonds in organophosphorus chemistry. (Figure presented.).
