Ferrocene/air double-mediated FeTiO₃-photocatalyzed semi-heterogeneous annulation of quinoxalin-2(1H)-ones in EtOH/H₂O

Chemical Communications, Год журнала: 2023, Номер 59(94), С. 14029 - 14032

Опубликована: Янв. 1, 2023

With both ferrocene and air as the redox catalysts, for first time, low-cost natural ilmenite (FeTiO3) was successfully used photocatalytic bond formations. Under assistance of a traceless H-bond, HCHO methylene reagent, variety imidazo[1,5-a]quinoxalinones were semi-heterogeneously photosynthesized in high yields with good functional group compatibility.
