Abstract

The use of Cu(OAc)₂ enables a dehydrogenative cross-coupling between two heteroarenes via disproportionation of the copper mediator. This synthetic protocol provides a concise and "green" access to unsymmetrical biheteroarenes bearing structural motifs of substantial utility in organic synthesis.
