Direct C-H activation of pyromellitic diimide (PMDI) is reported for the first time. The method avoids cumbersome pathways involving bromination usually required for further cross-coupling. Good to excellent yields of mono- and di-substituted PMDI derivatives can be obtained under optimized reaction conditions. The reaction scope was also explored, and the materials were characterized with respect to their thermal, optical, and electronic properties.
首次报道了均苯四甲酸二酰亚胺（PMDI）的直接C-H活化。该方法避免了通常用于进一步交叉偶联的涉及溴化的繁琐途径。在优化的反应条件下，可以获得良好至优异产率的单取代和二取代PMDI衍生物。还探索了反应范围，并对材料的热、光和电子性质进行了表征。
