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 intermediate, benzocinnoline
N-imide, is responsible for the activation of triplet
molecular oxygen to singlet oxygen that, in turn, promotes the synthesis
of carbazole.
