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.
4,4,4-三氟-3,3-二甲氧基丁酸(TDBA)的 Kolbe 电解产生了相应的均偶联产物 1,1,1,6,6,6-六氟-2,2,4,4-四甲氧基己烷,该产物可通过 TiCl4 处理后脱氢氯化转化为二烯。此外,TDBA 和 3-hydroxy-2-trifluoromethylpropionic acid 的交叉 Kolbe 产物可转化为四氢呋喃和 1-烯烃。
