Abstract
A tunable coupling or acetylation of phenol derivatives with diacetyl was enabled through the switch of the atmosphere and solvent induced by visible light under metal-free conditions. Symmetric and asymmetric diphenols or binaphthols were obtained under oxygen in water or 1,1,1,3,3,3-hexafluoroisopropanol, whereas phenol acetates were formed under argon in the presence of diacetyl and acetic acid. The possibility to control the chemo- and regioselectivities enriches the synthetic versatility of photoreactions.

Abstract
Over the last decade, visible-light photocatalysis has proved to be a powerful tool for the construction of N-heterocyclic frameworks, important constituents of natural products, insecticides, pharmacologically relevant therapeutic agents and catalysts. This account highlights recent developments and established methods towards the photocatalytic cascades for preparation of different classes of N-heterocycles, giving emphasis on our contribution to the field.
