Metal-free aromatic hydrogenation: Aniline to cyclohexyl-amine derivatives

Abstract

Hydrogenation of the N-bound phenyl rings of amines, imines, and aziridine is achieved in the presence of H 2 and B(C 6F 5) 3, affording the corresponding N-cyclohexylammonium hydridoborate salts. © 2012 American Chemical Society.
