Pd-Catalyzed Aerobic Oxidative Coupling of Arenes: Evidence for Transmetalation between Two Pd(II)-Aryl Intermediates
Pd-catalyzed aerobic oxidative coupling of arenes provides efficient access to biaryl compounds. The biaryl product forms via C-H activation of two arenes to afford a Pd(II)ArAr' intermediate, which then undergoes C-C reductive elimination. The key Pd(II)ArAr' intermediate could form via a "monometallic" pathway involving sequential C-H activation at a single Pd(II) center, or via a "bimetallic...
متن کاملA general gold-catalyzed direct oxidative coupling of non-activated arenes.
A gold-catalyzed mild and general oxidative homo-coupling of arenes using PhI(OAc)2 as the oxidant is described (13 examples, 31-81% yield).
متن کاملGold-catalyzed oxidative coupling reactions with aryltrimethylsilanes.
During continuing studies with a novel oxidative gold oxyarylation reaction, arylsilanes were found to be competent coupling partners, providing further evidence for an intramolecular electrophilic aromatic substitution mechanism. While providing yields complementary to those of the previously described boronic acid methods, the use of trimethylsilanes reduces the observation of homocoupling by...
متن کاملAerobic Oxidative Trifluoromethylation of Arenes Catalyzed by Phosphovanadomolybdic Acids
The trifluoromethyl (CF3) group is becoming of increasing importance in pharmaceuticals, agrochemicals, polymers, and liquid crystals because the physical and chemical properties of molecules, such as metabolic stability, membrane permeability, and bioactivity, can be remarkably modified by installation of CF3 group(s). Therefore, the development of efficient trifluoromethylation methods has at...
متن کاملVanadium-Catalyzed Regioselective Oxidative Coupling of 2-Hydroxycarbazoles
The first regioselective oxidative coupling of 2-hydroxycarbazoles is described. With a vanadium catalyst and oxygen as the terminal oxidant, dimers with an ortho-ortho' coupling pattern were obtained with high selectivity. Further oxidation led to ortho'-ortho' coupling to generate a tetramer, which provided insight that the atropisomerization barriers of the unsymmetrical biaryl bonds are muc...
