  日期：2014.9.5

  A zinc(II)/NHC system catalyzes the borylation of aryl halides with diboron (4) reagents in the presence of KOMe at rt. This transformation can be applied to a broad range of substrates with high functional group compatibility. Radical scavenger experiments do not support a radical-mediated process.

  作者：Shigehiro Asano、Seiji Kamioka、Yoshiaki Isobe

  DOI：10.1016/j.tet.2011.10.057

  日期：2012.1

  Suzuki–Miyaura cross-coupling reaction with 2-heteroarylboronic acids is generally challenging due to these acids easy decomposition. To overcome this problem, we developed a coupling method that uses 2-heteroaryl pinacol boronates in the presence of 1.0 mol % Pd(OAc)2 and 2.0 mol % S-Phos with 4 equiv amount of LiOH in dioxane and H2O at 80 °C for 30 min. This developed method allowed for the synthesis

  由于这些酸易于分解，因此与2-杂芳基硼酸的铃木-宫浦交叉偶联反应通常具有挑战性。为克服此问题，我们开发了一种偶合方法，该方法在1.0 mol％Pd（OAc）2和2.0 mol％S-Phos的存在下，在80％的二恶烷和H 2 O中于80摩尔下使用2-杂芳基频哪醇硼酸酯°C 30分钟。这种发达的方法允许从2-氯嘧啶基衍生物高产率地合成各种各样的2-杂芳基嘧啶，并且还可以用于由杂芳基氯化物制备各种联芳基衍生物。

  日期：2009.11

  A general method for the preparation of virtually any potassium trifluoroborate salt from the corresponding pinacolboronic ester is reported. Thus, conditions for an azeotropic removal of pinacol from the reaction mixture were found to afford the desired potassium trifluoroborates of sufficient purity (>95%) in nearly quantitative yields irrespective of the nature of the product. The utility of this
