Electrochemical cross-coupling reactions of sodium arenesulfinates with thiophenols and phenols

A green electrochemical oxidative cross-coupling protocol for the generation of thiosulfonates and sulfonate esters using sodium arenesulfinates and thiophenols/phenols is disclosed. The protocol involves using inorganic and non-toxic NaI as both redox catalyst and supporting electrolyte at room temperature without oxidant and base. The reactions provide good yields of products and tolerate broad substrate scope. The mechanistic studies revealed that the reactions proceed via a radical pathway for the formation of SO2–S and SO2–O bonds.

Catalyst-controlled selectivity in C-S bond formation: Highly efficient synthesis of C2- and C3-sulfonylindoles

Exploring a potential catalyst system for catalyst-controlled selectivity in C-S bond formation is a fascinating challenge. Herein, we described two novel and highly efficient methods for the selective synthesis of C2- and C3-sulfonylindoles showing good biological activities by employing iodide and copper catalysts, respectively. Mechanistic studies point to the crucial role of the electronic properties of the sulfonylated intermediates. I see two and I see three: Two novel and highly efficient methods for the selective synthesis of C2- and C3-sulfonylindoles by employing iodide and copper catalysts, respectively, are described.

Generation and alkylation of 2-boryl allylic sulfone anions

The deprotonation and electrophilic trapping of an allylic sulfone substituted at the 2 position by a pinacol boronate results in the formation of the corresponding alkylation products. The ability of the boronate ester to tolerate the sulfonyl carbanion suggests a broader application of the methodology to prepare a wide range of functionalized boronates.
