Reported herein is a fully orthogonal olefination, which involves the site- and E-selective coupling of aryl germanes with alkenes, tolerating otherwise widely employed coupling handles such as aromatic (pseudo)halogens (C-I, C-Br, C-Cl, C-F, C-OTf, C-OSO F), silanes and boronic acid derivatives as well as alternative functionalities. This unprecedented [Ge]-based oxidative Heck coupling proceeds at room temperature with high speed (10 min to 2 hours) and operational simplicity owing to its base-free and air-tolerant features.
本文报道了一种完全正交的烯基化反应,该反应涉及芳基锗烷与烯烃的位点选择性和E选择性偶联,能够兼容其他广泛使用的偶联基团,如芳族(拟)卤化物(C-I、C-Br、C-Cl、C-F、C-OTf、C-OSO₂F)、硅烷和硼酸衍生物以及其他官能团。这种前所未有的基于锗的氧化Heck偶联反应在室温下以高速(10分钟至2小时)进行,并且由于其无碱和耐空气的特性,操作简便。
