N‐alkylations of carbazoles with a variety of secondary and hindered primary alkyl iodides can be achieved by using a simple precatalyst (CuI) under mild conditions (0 °C) in the presence of a Brønsted base; at higher temperature (30 °C), secondary alkyl bromides also serve as suitable coupling partners. A Li[Cu(carbazolide)2] complex has been crystallographically characterized, and it may serve as

The use of light to facilitate copper-catalyzed cross-couplings of nitrogen nucleophiles can enable C-N bond formation to occur under unusually mild conditions. In this study, we substantially expand the scope of such processes, establishing that this approach is not limited to reactions of carbazoles with iodobenzene and alkyl halides. Specifically, we demonstrate for the first time that other nitrogen
