α-Diazo quinones were applied in an Ir(iii)-catalyzed direct C-H functionalization assisted by N-phenylacetamide for the construction of highly functionalized 2-hydroxy-2′-amino-1,1′-biaryl scaffolds in good to excellent yields. This strategy features ope

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.

4,2-Chloronitrobenzenediazonium ions in aqueous buffer solutions between pH 2.9 and 7.9 do not hydrolyze by dediazoniation as previous authors have assumed, but by denitration.The isomeric 2,4-compound reacts by denitration (ca. 70percent) and dechlorinat
