Abstract

Anodic oxidation-promoted SNAr reactions of electron-rich aryl fluoride were developed. The anodic oxidation of 4-fluoroanisole in hexafluoroisopropyl alcohol (HFIP) with K2CO3 led to SNAr-type hexafluoroisopropoxylation, and the reaction was completed with a catalytic electrical input. The results of cyclic voltammetry suggest that the radical cation of 4-fluoroanisole, which would react with the alkoxide of HFIP, is generated. Electron transfer between the intermediate and the starting material constructs the catalytic cycle, and the elimination of fluoride from the Meisenheimer complex produces the desired compound.

Abstract

Electrochemical organic synthesis has attracted attention as an environmentally friendly method for constructing heterocyclic compounds via carbon–heteroatom bond formation. Herein, we describe the representative examples of electrochemical reactions to produce heterocycles, and discuss them according to whether they involve direct or indirect electrolysis.

Electrochemical Synthesis of Sultone Derivatives via Dehydrogenative C–O Bond Formation 査読国際誌

記述言語：英語掲載種別：研究論文（学術雑誌）

Electrochemical dehydrogenative C-O bond formation for the synthesis of sultones was achieved. In the presence of K2CO3 and H2O, constant current electrolysis of [1,1'-biphenyl]-2-sulfonyl chloride afforded an aryl-fused sultone quantitatively. Under the optimized conditions, a variety of sultone derivatives were obtained. Control experiments suggest that the electrochemical oxidation of the sulfonates generated in situ would afford sulfo radical intermediates.

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Georg Thieme Verlag {KG}

<jats:p>An electrochemical cross-coupling reaction between arylboronic esters and aryllithiums was developed. The presence of Br− in the electrolyte was found to be essential for the reaction. NaBr was chosen as the electrolyte for its inexpensiveness and abundance, and also acted as a halogen mediator. The reaction proceeded under mild conditions to afford biaryls.</jats:p>
