The direct C—H functionalization of methylarenes is of great significance. Herein, a copper‐catalyzed oxidative C—N/C—S bond formation through benzylic C(sp3)—H functionalization, oxidation and cyclization of methylarenes is reported. Various 2‐arylbenzothiazoles have been synthesized in moderate to excellent yields with readily available o‐iodoaniline, potassium sulfide, and methylarenes as raw materials
2-haloaryl isothiocyanates and isocyanides to access benzo[d]imidazo[5,1-b]thiazoles has been realized efficiently under metal- and photocatalyst-free conditions. The reaction mechanism was explored by several preliminary experiments involvingreactive intermediate, free radical inhibitors, and corresponding photoelectric spectra. This protocol possesses some advantages over the previous methods such as

A visible-light-induced synthesis of N-H carbazoles from easily accessible 2,2′-diaminobiaryls in the absence of any external photosensitizer is reported. The process only requires tBuONO and natural resources, visible light, and molecular oxygen for the synthesis of N-H carbazoles. Experimental and computational studies support that the in situ formation of a visible-light-absorbing photosensitizing
