An original synthesis of 1,3-dithioles prepared from mesoionic 2-piperidino-5-aryl-1,3-dithiolium-4-thiolates is described. The reaction of the carbanion derived from 1,3-dithiole with carbon disulfide followed by alkylation to yield 2(1,3-dithiolan-2-ylidene)-1,3-dithiole is also reported. This synthesis of dithioles led to substituted tetrathiafulvalenes not accessible by our usual procedure.
描述了由介电的2-哌啶子基-5-芳基-1,3-二硫代-4-硫醇盐制备的1,3-二硫醇的原始合成。还报道了衍生自1,3-二硫醇的碳负离子与二硫化碳的反应,然后烷基化以生成2(1,3-二硫杂环戊-2-基)-1,3-二硫醇。二硫醇的这种合成导致我们通常的方法无法获得的取代的四硫富瓦烯。
