制备方法与用途

用途

2,6-二氟苯基硼酸频哪醇酯是一种羧酸酯类衍生物，广泛应用于药物中间体领域。

制备

在500 mL 的三口瓶中，加入10 g 1,3－二氟－2－溴苯、17 g 异丙醇频哪醇硼酸酯和210 mL 干燥的四氢呋喃。插好温度计，并抽掉空气后充氮气保护。降温至 － 78 ℃，用注射器慢慢加入36. 1 mL 正丁基锂，加完后继续在－78 ℃反应5 min。随后慢慢升至室温，继续反应20 min。之后，使用2 M 盐酸将体系调至pH =6～7，搅拌30 min 后静置分层。从水层中用乙酸乙酯萃取，合并有机层。再用无水硫酸钠干燥有机层，并蒸除溶剂。最后通过硅胶层析柱纯化，最终得到10 g 无色油状液体，收率为82.7%。

  （杂）芳基硼酸酯的原脱硼：直接与预水解途径和自/自催化

  摘要：

  一系列硼酸酯的碱催化水解（ArB(OR) 2 → ArB(OH) 2）和原脱硼化（ArB(OR) 2 → ArH）的动力学和机理，包括八种不同的多元醇和 10 种多氟芳基和杂芳基部分，已通过原位和停流 NMR 光谱（19 F、1 H 和11 B）、pH 速率依赖性、同位素夹带进行了研究，2H KIE 和 KS-DFT 计算。该研究揭示了硼酸酯在碱性水-有机条件下的现象稳定性非常微妙。与通常的假设相反，与相应的硼酸相比，酯化不一定赋予更高的稳定性。此外，酯水解为硼酸可以是整个原脱硼过程的主要成分，当 pH 值接近硼酸的 p K a时，自催化、自催化和氧化（酚类）催化作用增强酯。

  日期：2017.4.27

  C−H Borylation of arenes has been a subject of great interest recently because of its atom‐economy and the wide applicability of borylated products in value‐added synthesis. A new bis(silylene)cobalt(II) complex bearing a bis(N‐heterocyclic silylene)‐pyridine pincer ligand (SiNSi) has been synthesized and structurally characterized. It enabled the regioselective catalytic C−H borylation of pyridines

  由于芳烃的原子经济性和硼酸盐化产物在增值合成中的广泛应用，近年来，芳烃的CH硼化已引起人们极大的兴趣。合成了一种新的带有双（N-杂环甲硅烷基）-吡啶钳式配体（SiNSi）的双（甲硅烷基）钴（II）配合物，并对其结构进行了表征。它使吡啶，呋喃和氟化芳烃的区域选择性催化CH硼化成为可能。值得注意的是，与以前已知的催化体系相比，它对氟化芳烃的硼化具有互补的区域选择性，这表明N杂环亚甲硅烷基供体在金属催化的催化应用中具有巨大的潜力。

  A novel protocol for the transition metal-free 1,2-addition of polyfluoroaryl boronate esters to aldehydes and ketones is reported, which provides secondary alcohols, tertiary alcohols, and ketones. Control experiments and DFT calculations indicate that both the ortho-F substituents on the polyfluorophenyl boronates and the counterion K+ in the carbonate base are critical. The distinguishing features
