benzothiazoles or benzoxazoles is reported. This represents a first example of metal-catalyzed decarboxylative C–H heteroarylation of benzo-fused heterocycles. The transformation provides a convenientroute, with good yields and functional group tolerance, to various important arylheteroaryl and unsymmetrical biheteroaryl structural motifs.

The dehydrogenativecross-coupling (CDC) reaction of diversely substituted azoles, synergistically catalyzed by copper and cobalt, is reported. This protocol represents the first example of the use of air as an oxidant to carry out this chemical reaction. The process provides a convenient and economical method for the construction of valuable unsymmetrical bis-heteroaryl compounds, including bis-benzoazole
