Rh(I)-catalyzed decarbonylation synthesis of carbazoles via C–N cleavage

A one-pot Rh(I)-catalyzed synthesis of 9-H carbazoles via C–N bond cleavage by activation of aldehyde C–H bonds is reported. This protocol offers good yields and tolerates a broad range of functional groups. Based on the extensive control experiments, we propose a plausible decarbonylation mechanism.
