초록
The palladium-catalyzed amination of a variety of aryl chlorides has been accomplished by using di(dicyclohexylamino)phenylphosphine (1) as a bulky electron-rich monoaryl phosphine ligand. The optimized condition for the palladium-catalyzed amination of aryl chloride is the followings: aniline (3.0 mmol, 1.0 equiv), chlorobenzene (3.15 mmol, 1.05 equiv), ligand 1 (1 mol %, 0.03 mmol), KOtBu (4.5 mmol, 1.5 equiv), Pd2(dba)3 (1 mol %, 0.03 mmol), and toluene as solvent at reflux temperature. We report on couplings of various amines or chloroamines with chlorobenzenes and heteroaryl chloride. © 2011 Elsevier B.V. All rights reserved.
