一、引言在有机硫化物中,与相应的硫化物(硫醚)或碸比较起来,亚碸(R_2SO)是为人不很熟悉的一类化合物。某些亚碸(RSOR’)有旋光性和几何异构体存在,初步反映出亚碸结构上的特点。在亚碸里,由于硫原子的3d轨道参加成键,所以其中的硫-氧键可以表现出双鍵和半离子键(S~+—O~-)的性质。鉴于亚碸结构上的特点,目前除在有机化学中用作溶剂和反应试剂以外,还在无机及分析化学中用作溶剂、络合剂和萃取剂等方面有了新的进展。二甲基亚碸是亚碸中最简单的化合物。虽在1866年Saizew就已制备出来。但是,由于受了原料和制备方法上的限制,许多年来,一直未受到人们的重视。
I. INTRODUCTION In organic sulphides, as compared with the corresponding sulfides (thioethers) or sulfates, sulfates (R_2SO) are a class of compounds that are not well understood by humans. Some ossicles (RSOR ’) have optical rotation and geometric isomers exist, initially reflect the structural characteristics of the otter. In 亚 碸, the sulfur-oxygen bond can show the properties of double bond and half-ion bond (S ~ + -O ~ -) because the 3d orbital of sulfur atom participates in the bond. In view of the structural characteristics of the subfamily, in addition to being used as a solvent and reaction reagent in organic chemistry, new progress has been made in inorganic and analytical chemistry as a solvent, complexing agent and extractant. Dimethylsilyl is the simplest compound in the genus Ardisia. Although in 1866 Saizew has been prepared. However, due to the limitations of raw materials and preparation methods, people have not been paying attention to them for many years.
