A highly efficient ortho-heteroarylation of phenols with diverse electron-rich heteroarenes has been developed to forge heteroaryl-2-hydroxyphenyl structural motifs. The removal of the directing group and subsequent intramolecular cyclization make this protocol applicable in the rapid construction of π-conjugated heteroacenes.
