Frozen aryldiazonium chlorides have been investigated in radical alkene and arene functionalizations. Through freezing at – 84 °C, aryldiazonium chlorides, which otherwise show significant decomposition in aqueous solution after several hours at room temperature, can be stored for at least 20 days. In addition, the slow melting of aryldiazonium-containing ice cubes can serve as an alternative to syringe
已经在自由基烯烃和芳烃官能化中研究了冷冻的芳基重氮氯化物。通过在– 84°C下冷冻,芳基重氮氯化物在室温下几个小时后会在水溶液中显着分解,因此可以储存至少20天。另外,如果需要将重氮盐受控地添加到反应混合物中,则含芳基重氮鎓的冰块的缓慢熔化可以代替通常使用的注射泵。
