Potassium 3-oxa-ω-fluorosulfonylperfluoropentanoate (FO2SCF2CF2OCF2CO2K), a low-temperature trifluoromethylating agent for organic halides; its α-carbon-oxygen bond fragmentation
The trifluoromethylation of organichalides with FO2SCF2CF2OCF2CO2K (1) in DMF can be accomplished at 45 °C which is advantageous for thermally sensitive substrates. α-Carbon-oxygenbondfragmentation of 1 and the related β-carbon-oxygen bond scission are discussed.
在DMF中用FO 2 SCF 2 CF 2 OCF 2 CO 2 K (1)对有机卤化物进行三氟甲基化可以在45°C的温度下完成,这对热敏性基材是有利的。α的-碳-氧键断裂1和相关的β碳上-氧键断裂进行了讨论。
