以三乙胺为缚酸剂,1,1-双(2-羟基-5-甲基苯基)乙烷和二氯亚砜为原料,合成了双酚的亚硫酸酯的化合物2,10,12-三甲基-6-氧-12H-双苯并[d,g][1,3,2]-二氧硫杂八环,最佳合成的物质的量比为:双酚∶二氯亚砜∶三乙胺=1∶2.0∶2.2,反应时间为2 h,产品收率为72%(以双酚计)。标题化合物经元素分析、IR、1H NMR对产物进行了结构鉴定,并用X射线单晶衍射法确定其单晶结构。

A compound named 2, 10, 12-trimethyl-12H-dibenzo[d, g] [1,3,2]-dioxathiocin-6-oxide was synthesized with 1-1-ethylidenebis （4-methylphenol）, thionyl chloride. The results showed that the optimum conditions are as follows, n（bisphenol） ： n（thionyl chloride）s n（triethylamine）= 1： 2 ： 2.2 and reaction time2 h. The yield was 72%. The structure of the target compound was confirmed by elemental analysis, IR and ^1 H NMR. The crystal structure was determined by X-ray single crystal diffraction.
