A convenient method for conversion of (sp 3 )C-Fbonds to (sp 3 )C-Z (Z = I, SR, SeR, TeR) bonds has been developed. The reaction proceeds at room temperature using magnesium salts (Z-MgX). S N 2 mechanism for substitiution of primary alkyl fluorides with MgI 2 in ether was supported by the inversion of the stereochemistry of the carbon connecting to F.
已经开发了一种将 (sp 3 )CF 键转换为 (sp 3 )CZ (Z = I, SR, SeR, TeR) 键的简便方法。该反应在室温下使用镁盐 (Z-MgX) 进行。用 MgI 2 在醚中取代伯烷基氟化物的 SN 2 机制得到了连接到 F 的碳的立体化学反转的支持。
