A convenient methodology for perfluoroalkylation including trifluoromethylation of (hetero)arenes with perfluoroalkyl bromides was developed. Key for the success is the use of a specific cobalt-based nanocatalyst, which can be recycled at least up to 4 times. The scope of this first cobalt-catalyzed perfluoroalkylation is presented and detailed catalyst characterization (e.g. analytical STEM, XPS, and XRD) has been carried out.

使用钴纳米催化剂，实现全氟烷基溴与（杂）芳烃的实际全氟烷基化

开发了一种方便的全氟烷基化方法，包括用全氟烷基溴进行（杂）芳烃的三氟甲基化。成功的关键是使用特定的钴基纳米催化剂，该催化剂至少可以循环使用4次。介绍了该首次钴催化的全氟烷基化的范围，并进行了详细的催化剂表征（例如分析型STEM，XPS和XRD）。
