A Sulfoxide Reagent for One‐Pot, Three‐Component Syntheses of Sulfoxides and Sulfinamides**

Angewandte Chemie International Edition, 2022
Abstract Sulfoxides and sulfinamides represent versatile sulfur functional groups found in ligands, chiral auxiliaries, and bioactive molecules. Canonical two‐component syntheses, however, rely on substrates with a preinstalled C−S bond and impede efficient and modular access to these sulfur motifs.

Electrochemical oxidations of thioethers: Modulation of oxidation potential using a hydrogen bonding network

Electrochemistry Communications, 2019
A highly efficient chemo-selective electrochemical oxidation of thioethers to sulfoxides and sulfones was developed. The hydrogen bonding network generated from hexafluoro-2-propanol (HFIP) and acetic acid (AcOH) plays an important role in the modulation
