We reported a photo-induced dehydrogenative N-N coupling of diarylimines, diarylamines, carbazoles, and anilines. This homo-coupling reaction only requires the combination of di-tert-butyl peroxide (DTBP) and light irradition. The protocol is simple, catalyst- and metal-free, and has a good substrate scope. Preliminary mechanistic studies suggest that the reaction proceeds via photo-induced homolytic cleavage of the peroxide followed by hydrogen atom transfer leading to the formation of N-centered radicals.
We report a photo-induced dehydrogenative N-N coupling of diarylimines, diarylamines, carbazoles, and anilines. These homo-coupling reactions require only the combination of readily available di-tert-butyl peroxide (DTBP) and light irradition. The operationally simple protocol works under catalyst- and metal-free conditions and exhibits a good substrate scope. Preliminary mechanistic studies indicate that the reaction proceeds via photo-induced homolytic cleavage of the peroxide followed by hydrogen atom transfer leading to the formation of N-centered radicals.
