The first examples of molecules in which carbaborane clusters are linked via a simple CC double bond, and which constitute model compounds for boronated polydiacetylenes, are reported; double metallation of one of these molecules affords a unique closo–pseudocloso bis(carbametallaborane).
报告中首次举例说明了通过简单的 CC 双键连接碳硼烷簇的分子,这些分子构成了硼化聚二乙烯的模型化合物;对其中一个分子进行双金属化处理后,可得到独特的闭锁-假闭锁双(氨基甲硼烷)。
