摘要
摘要 在氩气下处理邻碳硼烷、正丁基锂、硫和 Me4CpCo(CO)I2，可得到半夹心 16e 碳硼烷络合物 Me4CpCo[S2C2B10H10]。Me4CpCo[S2C2B10H10] 与 PPh2Me、PPhMe2 和 PMe3 反应，分别得到加成产物 Me4CpCo[S2C2B10H10](PPh2Me) (I)、Me4CpCo-[S2C2B10H10](PPhMe2) (II)、Me4CpCo[S2C2B10H10](PMe3) (III)。对 I、II 和 III 进行了红外、核磁共振、元素分析和质谱表征。I 和 III 还通过单晶 X 射线衍射分析（CCDC 编号：2245287（I）和 2245288（III））进行了表征。对化合物 I、II 和 III 的紫外光谱和荧光光谱特性进行了测试。复合物 I、II 和 III 在乙腈溶液中的紫外光谱结果显示，波段分别位于 412、399 和 401 纳米。络合物 I、II 和 III 的荧光光谱结果显示，最大发射峰约在 405 纳米波长处。
Reactivity of Half-Sandwich 16e Carborane Complex Me4CpCo[S2C2B10H10] with Phosphorous Compounds
Treatment of o-carborane, n-butyllithium, sulfur and Me4CpCo(CO)I2 under argon leads to half-sandwich 16e carborane complex Me4CpCo[S2C2B10H10]. Me4CpCo[S2C2B10H10] reacts with PPh2Me, PPhMe2, PMe3 to afford addition products Me4CpCo[S2C2B10H10](PPh2Me) (I), Me4CpCo-[S2C2B10H10](PPhMe2) (II), Me4CpCo[S2C2B10H10](PMe3) (III), respectively. I, II and III have been characterized by IR, NMR, elemental analysis, mass spectrum. I and III have also been characterized by single-crystal X-ray diffraction analysis (CCDC nos. 2245287 (I) and 2245288 (III)). The UV and fluorescent spectra properties of the compounds I, II and III have been tested. The UV spectra results of complexes I, II and III in acetonitrile solution show that the bands are located at 412, 399 and 401 nm, respectively. The fluorescence spectra result of the complexes I, II and III exhibit maximum emission peaks at about 405 nm.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
