Preparation of Trifluoromethylated Compounds via Anodic Oxidation of 4,4,4-Trifluoro-3,3-dimethoxybutyric Acid

Abstract

Abstract The Kolbe electrolysis of 4,4,4-trifluoro-3,3-dimethoxybutyric acid (TDBA) gave corresponding homo-coupling product, 1,1,1,6,6,6-hexafluoro-2,2,4,4-tetramethoxyhexane, which could be converted to the diene by treating with TiCl4 followed by dehydrochlorination. Furthermore, the crossed Kolbe product from TDBA and 3-hydroxy-2-trifluoromethylpropionic acid was converted to tetrahydrofurans and an 1-olefine.
