An evaluation of both a visible‐light‐ and UV‐light‐mediated synthesis of carbazoles from various triarylamines with differing electronic properties under continuous‐flow conditions has been conducted. In general, triarylamines bearing electron‐rich groups tend to produce higher yields than triarylamines possessing electron‐withdrawing groups. The incorporation of nitrogen‐based heterocycles, as well

An increasingly sustainable photochemical synthesis of carbazoles was developed using a catalytic system of Fe(phen)(3)(NTf2)(2)/O-2 under continuous flow conditions and was demonstrated on gram scale using a numbering-up strategy. Photocyclization of triaryl and diarylamines into the corresponding carbazoles occurs in general in higher yields than with previously developed photocatalysts.
