Starting from a [(MeOC^N^C)AuCl] complex as precursor, a direct substitution by C,H-activation from sp-, sp2- or sp3-C,H-bonds under basic conditions in a planetary ball mill was achieved. Because of the extraordinary photophysical properties of the target compounds, this protocol provides an easy access to a highly valued complex class. In contrast to existing protocols, no pre-functionalization of
从 [( MeO C^N^C)AuCl] 络合物作为前体开始,在行星球的基本条件下通过 sp-、sp 2 - 或 sp 3 -C,H-键的 C,H-活化直接取代磨机已实现。由于目标化合物具有非凡的光物理特性,该协议可以轻松获得高价值的复杂类别。与现有方案相比,不需要对起始材料进行预官能化,并且可以避免使用昂贵的过渡金属催化剂,这使得该应用对于工业目的也有吸引力。此外,该方法不限于钳配合物,这通过螯合型[(tpy)AuCl 2 ]配合物的取代得到证明。
