Abstract: We have recently developed a method for the synthesis of pyrrolidines and piperidines via intramolecular C–H amination of N-fluoride amides using [TpxCuL] complexes as precatalysts [Tpx = tris(pyrazolyl)borate ligand and L = THF or CH3CN].… read more here.

Abstract: An effective and operationally simple protocol is reported for the synthesis of versatile carbazoles. With water as a co-solvent, visible-light rather than various metals is used to facilitate the conversion of readily available 2-azidobiphenyls under… read more here.
