A mild and practical cobalt-catalyzed defluoroborylation of fluoroarenes is presented for the first time. The method permits straightforward functionalization of fluoroarenes, with high selectivity for borylation of C–F over C–H bonds, and a tolerance for aerobic conditions. Furthermore, two-step 18F-fluorination was achieved for expanding the scope of 18F-positron emission tomography probes.
首次提出了温和实用的钴催化的氟代芳烃脱氟硼化反应。该方法可实现氟代芳烃的直接功能化,对C–F相对于C–H键的硼化具有很高的选择性,并且对有氧条件具有耐受性。此外,实现了两步式18 F氟化反应,以扩展18 F正电子发射断层扫描探头的范围。
