It was found that sodium salt of 1,2-benzisothiazole-3(2H)-thione 1,1-dioxide (thiosaccharin) readily reacted with alkyl halide affording 3-(alkylthio)-1,2-benzisothiazole 1,1-dioxide (3). Treatment of 3 with piperidine produces the corresponding alkanethiol in situ quantitatively and subsequent treatment with various electrophiles gives the corresponding sulfides and thiocarboxylic S-esters in good yields.
发现1,2-苯并异噻唑-3(2H)-硫酮1,1-二氧化物(硫糖精)的钠盐与烷基卤化合物容易反应,生成3-(烷硫基)-1,2-苯并异噻唑1,1-二氧化物(3)。将3与哌啶反应,现场定量地生成相应的烷硫醇,随后与各种亲电试剂反应,能够以良好产率得到相应的硫化物和硫代羧酸S-酯。
