We developed an efficient synthesis of biaryls by a dirhodium(II)-catalyzed aromatic C?H arylation with diazo quinones. The new biaryl synthesis can be performed under mild and neutral conditions and without directing group chelation assistance. The reaction tolerates various functionalities and is applicable to a broad range of aromatics. The regioselectivity of the C?H arylation was often high and predictable. The synthetic utility of the method was demonstrated by the late-stage modifications of a series of pharmaceuticals and functional materials as well as a short synthesis of a transthyretin amyloid inhibitor.

Diazo compounds as coupling partners are efficiently applied to Ir(III)-catalyzed direct C-H functionalization of arylphos-phine oxides. Involving C-H activation, carbene insertion, and tautomerism, this reaction proceeds under mild conditions, thus proving an approach to the synthesis of MOP-type ligand precursor in a single step. The utility of this transformation has been further demonstrated in ligand synthesis as well as in the construction of phosphole framework.
