摘要

Linear diaryliodoniums often undergo only single arylation and leave equivalent aryl iodide as waste. Herein, we demonstrate that linear unsymmetrical diaryliodoniums could be tuned by a dual nickel/palladium metal system to accomplish one-pot cyclization/arylation. Of note, the in situ generated benzoxazole motifs could then be utilized as directing groups for subsequent C-H activated arylation from the often unwanted aryl iodide, exhibiting good reactions with atom economy and regioselectivity.
