The invention provides catalysts and methods for preparing boronate esters. The methods can include the borylation of a secondary or primary C—H bond, for example, by contacting a reactant having a methylene or methyl and a diboron bis-ester in the presence of an effective catalyst. The contacting can be in the presence of an iridium complex, to effect borylation of the secondary or primary C—H bond, thereby providing the boronate ester. The boronate esters can be readily isolated and/or converted into other useful compounds and intermediates.
本发明提供了制备
硼酸酯的催化剂和方法。该方法可以包括通过在有效催化剂存在下,使具有亚甲基或甲基和二
硼双酯的反应物接触,从而使次级或一级C-H键发生
硼化。接触可以在
铱配合物的存在下进行,以使次级或一级C-H键发生
硼化,从而提供
硼酸酯。
硼酸酯可以容易地被分离和/或转化为其他有用的化合物和中间体。
