unprecedented dihydro-1,3-azaborole derivatives 16. The tolane-derived example 16a was deprotonated and used as a ligand in organometallic chemistry. Compounds 16 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
(Fmes)BH2·SMe2 试剂 (7) 在方便的三组分反应中依次与乙炔和二甲苯基异腈反应,得到一系列前所未有的二氢-1,3-氮杂硼衍生物 16。 甲苯衍生实例 16a被去质子化并用作有机金属化学中的配体。通过用异腈处理,化合物 16 作为直接合成各种二氢-1,3-氮杂硼烷衍生物的起始材料。几种二芳基二氢-1,3-氮杂硼化合物显示出有趣的光物理特性,例如聚集诱导发射和高荧光量子产率。
