Controllable chemoselectivity in the reaction of 2H-indazoles with alcohols under visible-light irradiation: synthesis of C3-alkoxylated 2H-indazoles and ortho-alkoxycarbonylated azobenzenes

A high chemoselectivity in the visible-light-induced reaction of 2H-indazoles with alcohols controlled by the reaction atmosphere (N2 or O2) was achieved. Under a N2 atmosphere, an alkoxylation of 2H-indazoles with alcohols in the presence of Mes-Acr+ClO4− as a photosensitizer and Selectfluor as an...
