Oxidative 1,2-Difunctionalization of Ethylene via Gold-Catalyzed Oxyarylation
摘要:
Under the conditions of oxidative gold catalysis, exposure of ethylene to aryl silanes and alcohols generates products of 1,2-oxyarylation. This provides a rare example of a process that allows catalytic differential 1,2-difunctionalization of this feedstock chemical.

Site‐selective borylation of simple arenes was realized in one pot via an electrophilic thianthrenation/Pd‐catalyzed borylation sequence. The key to achieve this operatically simple process is the use of Pd catalysis, which could tolerate the solvent and acidic conditions used in the thianthrenation step. This protocol features mild conditions, broad functional group tolerance, and simple manipulations

versatile sulfonium salt via highly electrophilic phenoxathiine or thianthrenedication intermediate which can be readily generated from its sulfoxide with tri-fluoromethanesulfonic anhydride. Preliminary mechanistic study implied that the remarkable para selectivity might be related to the incredible electrophilicity of thianthrenedication intermediate. The versatility of this approach was demonstrated

Convergent paired metal electrocatalysis enables the direct use of simple primary and secondary aliphaticacids as coupling partners for C(sp2)−C(sp3) bond formation by radical decarboxylation. This new electrophotocatalytic method features a broad substrate scope, wide functional-group tolerance, and could be used for late-stage functionalization of complex molecules.
