copper(I)-catalyzed tandemreaction of N- and O-arylations of 2-[N-(2-chlorophenyl)amino]phenols was developed, by which a series of structurally novel N-aryl phenoxazines were synthesized efficiently. This success owes much to the discovery of highly efficient homogeneous copper(I)-catalyzed intramolecular O-arylation of chlorobenzenes under ligand-free-like conditions. Since 2-[N-(2-chlorophenyl)amino]phenols
