Abstract : Metallocarboranes of iron, cobalt and nickel have been prepared by the direct reaction of the small polyhedral carboranes 1,5-C2B3H5, 1,6-C2B4H6, or 2,4-C2B5H7 with organometallic and metal carbonyl reagents in the gas phase or in solution, without the use of a prior cage-opening step. Novel 6-vertex cages as well as 7-vertex species were obtained, including mono-, di-, and trimetallocarborane
摘要 : 铁、钴和镍的金属碳硼烷是通过小多面体碳硼烷 1,5-C2B3H5、1,6-C2B4H6 或 2,4-C2B5H7 与有机金属和金属羰基试剂在气相或在解决方案中,无需使用先前的笼子打开步骤。获得了新的 6 顶点笼以及 7 顶点物种,包括单、二和三金属碳硼烷物种。根据硼 11 和质子核磁共振谱,为新化合物指定了分子结构。在 HCBH 质子 - 质子耦合的基础上解释了几种钴碳硼烷物种表现出的碳硼烷 CH 质子核磁共振信号的精细结构。(修改后的作者摘要)
