Efficient borylation reaction of diazonium salts in water is realized for the first time by using easily prepared, highly emissive and crystalline carbon dots. Electron-donating and electron-withdrawing groups on diazonium salts were well tolerated with moderate to good conversion efficiency. Compared with widely used metal complexes, organic dyes and quantum dots, the approach presented herein uses carbon dots, which are nontoxic and possess good biological and medicinal compatibility and high reactivity. Therefore, this approach presents a new prospective use for carbon dots in green chemistry.
首次使用易于制备、高发光且结晶的碳点实现了水中的高效重氮盐硼化反应。重氮盐上的供电子和吸电子基团具有良好的耐受性，转化率适中到良好。与广泛使用的金属配合物、有机染料和量子点相比，本文所提出的方法使用了碳点，其具有无毒、良好的生物和医学相容性以及高反应性。因此，该方法为碳点在绿色化学中的应用提供了新的前景。
