possible to prepare carbon-based analogues of the Merrifield resin by electrochemicalreduction of diazonium salts or oxidation of aryl acetates on high specific surface area carbon felts. These modified felts can undergo further reactions: nucleophilic substitution, Suzuki reaction, and finally reductiveelectrochemicalcleavage, taking advantage of the conductivity of the carbon felt. This provides

The synthesis, characterization, and evaluation of a Schiff base Cu (II) complex functionalized boehmite nanoparticles (Cu‐complex‐boehmite) as a new catalyst for oxidation of sulfides and thiols in the presence of hydrogen peroxide with complete selectivity and high conversion under solvent‐free and mild reaction conditions were reported. Characterization of the catalyst was performed with various

It was found that the combination of triflic anhydride/potassiumiodide was an effective promoter for the deoxygenation of sulfoxides and gave the corresponding sulfides in excellent yield in acetonitrile at room temperature. It is worth mentioning that this reagent system is chemoselective and tolerates various functional groups, such as alkene, ketone, ester, aldehyde, acid, and oxime.
