α,α′-Dioxothione 1a and ortho-thioquinones 2a and 2b are able to react with several phenols and N,N-dimethylaniline to give the corresponding alkyl aryl or diaryl sulfides. The mechanism of this reaction was proved to be an electrophilic aromatic substitution undergone by the highly polarised carbon−sulfur double bond. Following this procedure, the atropoisomeric biphenyl compound 26 was also prepared
α,α'-二氧硫酮 1a 和邻硫醌 2a 和 2b 能够与几种酚和 N,N-二甲基苯胺反应生成相应的烷基芳基或二芳基硫化物。该反应的机理被证明是由高度极化的碳硫双键进行的亲电芳香取代。在该程序之后,还制备了阻转异构联苯化合物26。
