A series of pyridine-2-phenolate-6-(σ-aryl) [OCH2 N,C] group 4 bis(benzyl) precatalysts, featuring a flexible O,N-donor chelate, have been prepared and characterized by multinuclear NMR spectroscopy. These complexes adopt C1/su
Selective Suzuki-Miyaura monocouplings with symmetrical dibromoarenes and aryl ditriflates for the one-pot synthesis of unsymmetrical triaryls

The various parameters that would permit selective Suzuki-Miyaura monocouplings of symmetrical dihaloarenes were studied. High selectivity and efficiency can be obtained for a broad range of substrates by using operationally simple conditions and widely available reagents. The 38 different examples described provide a valuable toolbox for the rapid access to unsymmetrical triaryls, as illustrated by the preparation of diarylpyridine 8, terphenyl 9, and diarylpyrrole 10. By studying several key parameters, the factors that allow selective Suzuki-Miyaura monocoupling of symmetrical dihaloarenes have been outlined. This study serves as the basis for the efficient synthesis of unsymmetrical triaryls from symmetrical dibromoarenes and aryl ditriflates by a one-pot desymmetrizing double Suzuki-Miyaura coupling.
