A series of redox-responsive ferrocenyl-substituted boranes and boronic esters were synthesized. Oxidation of the ferrocenyl ligand to the ferrocenium resulted in a drastic increase in the Lewis acidity beyond the strength of SbF , which was investigated experimentally and computationally. The resulting highly Lewis acidic boron compounds were used for catalytic C-F and S-F bond activation.
合成了一系列氧化还原响应性二茂铁基取代的硼烷和硼酸酯。二茂铁配体氧化为二茂铁鎓导致路易斯酸度急剧增加，超过了SbF的强度，对此进行了实验和计算研究。所得的高路易斯酸性硼化合物用于催化C-F和S-F键活化。
