二乙基锌 (C2H5)2Zn, 或者简写为 DEZn, 是一种有机化合物,由锌连接两个乙基获得。这种无色的液体是一种有机化学中市售的常用试剂,它通常为正己烷正庚烷甲苯溶液。

合成

在1848年時,爱德华·弗兰克兰首先發現此化合物,是用鋅和碘乙烷製備,是第一個發現的有機鋅化合物[1][2]。後來為了改進合成過程,改用二乙基汞為反應物[3]。現在的製備方式是將一比一的碘乙烷和溴乙烷混合物和锌铜偶反應,後者是鋅和銅的合金,可以產生有反應性的鋅[4]

安全性

二乙基锌和水反应非常剧烈,且在空气暴露下易燃。使用它必须在惰性气体保护下进行。

Hypothetical concept in physics In physics, there is a speculative hypothesis that, if there were a black hole with the same mass, charge and angular momentum as an electron, it would share other properties of the electron. Most notably, Brandon Carter showed in 1968 that the magnetic moment of such an object would match that of an electron.[1] This is interesting because calculations ignoring special relativity and treating the electron as a small rotating sphere of charge give a magnet…
