Syntheses and Properties of-Benzene（Tetralin）-Cyclopentadienyliron Closo-Halohydroborates 张伦 first-author 胡培植 向进福 张国敏 将闭式-卤代氢硼酸根(B 10 H 2 Cl 8 2- ,B 10 Cl 10 2- 、B 10 H 2 Br 8 2- 、B 10 H 4 I 6 2- 、B 12 H 3 Cl 9 2- 、B 12 H 4 Br 8 2- )与π-苯（四氢萘）-π-环戊二烯基铁反应,共合成了八个新化合物。通过元素分析和红外光谱确定了化合物的组成。差热分析结果表明,化合物均具有较好的热稳定性;当阴离子相同时,含苯和四氢萘的化合物的分解温度相近,当阳离子相同且阴离子中硼原子个数相同时;其热稳定性次序为:氯代物 > 溴代物 > 碘代物 > 未卤代物。 In this paper, 8 new compouuds have been synthesized by the reaction between closo-halo-hydroborate ions (B 10 H 2 Cl 8 2- , B 10 Cl 10 2- , B 10 H 2 Br 8 2- ,B 10 H 4 I 6 2- , B 12 H 2 Cl 9 2- and B 12 H 4 Br 8 2- ) and π-benzene （tetralin） -π-cyclopentadienyliron cations, Their composition has been identified by elemental analyses and IR spectra. The DTA results show that these compounds are thermally stable, and when the anion is the same, the decomposition temperature of benzene-containing and tetralin-containing compounds are about the same; when the cation is the same, and the number of the boron atoms in the anions is the same, the order of the thermal stability is chloro- > bromo- > iodo- > nonhalo-compounds. 1985-02-01 2021-04-01 2
