We report a new in situ borylation method using tetrakis(dimethylamino)diboron, DMA₄B₂, in the presence of a diol. Our method uses standard borylation conditions and readily available Pd-catalysts. The scope of this method includes aryl halides and triflates as well as vinyl halides and triflates. The method successfully works with a broad range of diols, enabling the selection of the best boronic ester for subsequent Suzuki coupling.

使用四（二甲基氨基）二硼硼化有机卤化物和三氟甲磺酸酯

我们报告了一种新的原位硼化方法，使用四（二甲基氨基）二硼，DMA ₄ B ₂，在二醇的存在下。我们的方法使用标准的硼化条件和现成的Pd催化剂。该方法的范围包括芳基卤化物和三氟甲磺酸酯以及乙烯基卤化物和三氟甲磺酸酯。该方法成功地与多种二醇一起使用，从而能够为随后的Suzuki偶联选择最佳的硼酸酯。
