Abstract
Visible light mediated synthesis of benzoxazoles from benzanilides under an air atmosphere at room temperature is reported using eosin Y as an organophotoredox catalyst by functionalization of C-H/C-O bond formation.This methodology accepts a broad range of functional groups and affords the benzoxazoles by transition-metal-free organic photoredox catalysis under very mild conditions.
