title: C-H arylation of azaheterocycles: a direct ligand-free and Cu-catalyzed approach using diaryliodonium salts.
abstract: An efficient and high yielding Cu-catalyzed direct C-H arylation of azaheterocycles including oxadiazoles, thiadiazoles, benzoxazoles and benzothiazoles has been achieved by employing easily accessible diaryliodonium salts.
