The photoredox-mediated direct intermolecular C−Hfunctionalization of substituted indoles, pyrroles, and furans with diethyl bromomalonate is described, utilizing the visible light-induced reductive quenching pathway of Ru(bpy)3Cl2. An analysis of reductive quenchers and mechanistic considerations has led to an optimized protocol for the heteroaromatic alkylations, providing products in good yields
