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.

Palladium-Catalyzed Cyanation under Mild Conditions: A Case Study to Discover Appropriate Substrates among Halides and Pseudohalides

A case study has been effectively carried out to identify a suitable substrate among halides and pseudohalides for the palladium-catalyzed cyanation reactions under mild conditions. Among the various substrates considered for evaluation, aryl pentafluorobenzenesulfonates and nonaflates were identified to be the best substrates when compared to corresponding halides and pseudohalides. The substoichiometric use of nontoxic, environmentally benign potassium hexacyanoferrate as a cyanide source and exceptionally milder conditions further highlights the significance of the protocol developed. A wide range of electronically biased and sterically challenging substrates provided the corresponding the nitriles in good to excellent yields.

Electron Donor-Acceptor Complex Enabled Decarboxylative Sulfonylation of Cinnamic Acids under Visible-Light Irradiation

Visible-light-induced decarboxylative sulfonylation of cinnamic acids with aryl sulfonate phenol esters enabled by the electron donor-acceptor complex is developed. The method offers a mild and green approach for the synthesis of vinyl sulfones with excellent functional group compatibility under photocatalyst and oxidant-free conditions.
