From an equimolar mixture of DMSO and SbCl5 in carbon tetrachloride, a DMSO–SbCl5(1 : 1) complex (1) was formed as a white precipitate in a quantitative yield. The structure of 1 was determined by X-ray crystallographic analysis. Butyraldehydes, para-substituted benzaldehydes and benzils were obtained by the oxidation of butylalcohols, para-substituted benzylalcohols and benzoins using 1 as an oxidizing agent.
在四氯化碳中加入等摩尔的二甲基亚砜(DMSO)和氯化锑(SbCl5)混合物后,生成了二甲基亚砜-氯化锑(SbCl5)(1:1)复合物(1),呈白色沉淀,收率极高。通过 X 射线晶体分析确定了 1 的结构。以 1 为氧化剂,通过氧化丁基醇、对位取代的苄基醇和安息香,得到了丁醛、对位取代的苄基醛和苯甲酰苯。
Investigation of the electronic structure of SnCl4L2, TiCl4L2 and SbCl5L complexes by X-ray fluorescence spectroscopy
Abstract The electronicstructure of SbCl 5 L complexes has been analyzed on the basis of the fluorescence spectra of the sulfur and chlorine atoms as well as quantum chemical XαDV and PM3 calculations. The results have been compared with the corresponding data for SnCl 4 L 2 and TiCl 4 L 2 complexes. An increase in electron density on the chlorine atoms accompanied by a decrease on the central metal
摘要 基于硫和氯原子的荧光光谱以及量子化学XαDV和PM3计算,分析了SbCl 5 L配合物的电子结构。已将结果与 SnCl 4 L 2 和 TiCl 4 L 2 配合物的相应数据进行了比较。对于根据其稳定性排列的配合物,已观察到氯原子上电子密度的增加伴随着中心金属原子的减少。Sn、Sb 和 Ti 与二甲基硫醚配合物根据其稳定性增加的排列与配合物在硫原子上的电子密度方面的顺序不一致。
