  Metal-Free Chlorodeboronation of Organotrifluoroborates

  摘要：

  A mild and metal-free method for the chlorodeboronation of organotrifluoroborates using trichloroisocyanuric acid (TCICA) was developed. Aryl-, heteroaryl-, alkenyl-, alkynyl-, and alkyltrifluoroborates were converted into the corresponding chlorinated products in good yields. This method proved to be tolerant of a broad range of functional groups.

  摘要：

  芳基硼酸作为试剂和目标结构在各种有用的应用中变得越来越重要。最近，报道了使用原子经济的四羟基二硼（BBA）试剂在钯催化下合成芳基硼酸。钯的高成本，加上钯和铜催化工艺的一些限制，促使我们开发一种替代方法。因此，已经制定了使用四羟基二硼（BBA）对芳基和杂芳基卤化物和拟卤化物进行镍催化的硼基化反应。该反应被证明具有广泛的官能团耐受性并适用于许多杂环体系。据我们所知，这里提供的例子代表了在室温下进行的唯一有效的镍催化宫浦硼化反应。

  reaction of aryl bromides. Bis-boronic acid (BBA), was used, and the borylation reaction was performed using a simple procedure at a mild temperature. Under mild conditions, aryl bromides were converted to arylboronic acids directly without any deprotection steps and purified by conversion to trifluoroborate salts. The functional group tolerance was considerably high. The mechanism study suggested that
