o-Carborane derivatives with precisely defined patterns of substitution have been prepared from 8,9,10,12-I4-1,2-closo-C2B10H8 by replacing the iodine atoms, bonded to four adjacent boron vertices in the cluster, with allyl, and subsequently 3-hydroxypropyl groups. The resulting structures, comprising four pendant arms and two reactive vertices located on opposite sides of a central o-carborane core, can be envisaged as versatile precursors for dendritic growth.
通过用烯丙基以及随后的 3-羟基丙基取代与簇中四个相邻硼顶点结合的碘原子,我们从 8,9,10,12-I4-1,2-closo-C2B10H8制备出了具有精确定义的取代模式的邻碳硼烷衍生物。由此产生的结构包括四个垂臂和位于中央邻碳硼烷核心相对两侧的两个活性顶点,可被视为树枝状生长的多功能前体。
