The (Fmes)BH·SMe reagent () reacts sequentially with an acetylene and, e.g., xylylisonitrile in a convenient three-component reaction to give a series of unprecedented dihydro-1,3-azaborole derivatives . The tolane-derived example was deprotonated and used as a ligand in organometallic chemistry. Compounds served as the starting materials for the straightforward synthesis of various dihydro-1,3-azaborinine derivatives by treatment with an isonitrile. Several diaryldihydro-1,3-azaboroles showed interesting photophysical properties such as aggregation-induced emission and high fluorescence quantum yields.
(Fmes)BH·SMe 试剂（）与乙炔、例如二甲苯异腈依次反应，在方便的三组分反应中生成一系列前所未有的二氢-1,3-氮杂硼烷衍生物。基于甲苯的例子 被脱质子并用作为有机金属化学中的配体。化合物 用作起始材料，通过与异腈反应可直接合成各种二氢-1,3-氮杂硼啶衍生物。几种二芳基二氢-1,3-氮杂硼烷显示出有趣的光物理性质，如聚集诱导发射和高荧光量子产率。
