  Synthesis, electrochemical behavior and EPR study of organometallic [5]trovacenylthiol (η7-C7H7)V(η5-C5H4SH) and structural characterization of ansa-trithio[3]trovacenophane

  摘要：

  Organometallic paramagnetic [5]trovacenylthiol (3(center dot)) was prepared by acidification of lithium [5]trovacenylthiolate 2(center dot), which was synthesized via elemental sulfur oxidative insertion to C-Li bond of [5] trovacenyllithium. [5]Trovacenylthiol (3(center dot)) was investigated by means of cyclic voltammetry and electron paramagnetic resonance (EPR). However, the reaction of concentrated DME solution of 2(center dot) with S2Cl2 unprecedentedly afforded ansa-trithio[3]trovacenophane (6(center dot)), which was demonstrated by X-ray diffraction analysis. Furthermore, three efficient strategies have been explored to construct S-C, S-Si bond of organometallic alkyl, aryl [5]trovacenyl sulfides (7(center dot), 8(center dot), 9(center dot)) and silylthioester (10(center dot)) in the absence of transition-metal catalyst under mild reaction conditions.

  The paramagnetic bis(5trovacenyl)dichalcogenides(η7-C7H7)V(η5-C5H4-E–E–η5-C5H4)V(η7-C7H7) 2·· (E = S), 3·· (E = Se), and 4·· (E = Te) were prepared by a novel path in which the elemental chalcogen atoms serve as suppliers of the hetero-atoms and as oxidants in the final step. Compounds 2·· and 4·· were analyzed by single-crystal X-ray diffraction analyses. Cyclic voltammetry revealed that redox splitting

  顺磁性双(5trovacenyl)二硫属元素化物(η7-C7H7)V(η5-C5H4-E–E–η5- )V(η7- ) 2·· (E = S), 3·· (E = Se),和 4·· (E = Te) 是通过一种新的途径制备的，其中元素硫族原子作为杂原子的供应者和最后一步中的氧化剂。化合物2··和4··通过单晶X射线衍射分析进行分析。循环伏安法显示2··-4··的氧化还原分裂没有被解决，即连续氧化还原步骤的电位差小于70 mV。通过EPR光谱和磁化率计对化合物2··进行了详细研究。EPR 光谱清楚地证明了两个不成对电子的自旋交换耦合，它们位于钒中心轨道 (51V, I = 7/2), |JEPR(2··)| = 0.65 厘米–1。相当大的值 Jχ(2··) = –1.36 cm–1 是从磁化率计获得的。
