alkyne-1-thiolate gives new tetrathiafulvalene-type vinylogue extended π-donors in a one pot reaction. The solvent-/base-system used (acetonitrile/NaH) was optimised for the synthesis of 1,3-dithiole-2-thiones via this route. Efficient synthesis of the important 4-formyl-1,3-dithiol-2-thione and its coupling to 2,6(7)-bisformyltetrathiafulvalene is presented. Preparation of a number of new 1,4-dithiafulvenes
用碱裂解1,4-二硫富富烯取代的1,2,3-噻二唑并二聚化生成的炔基-1-硫醇酯在一次反应中得到了新的四硫富瓦烯型乙烯基延伸的π供体。通过这种途径,优化了所用的溶剂/碱体系(乙腈/ NaH)以合成1,3-二硫代-2-硫酮。提出了重要的4-甲酰基-1,3-二硫醇-2-硫酮的有效合成方法及其与2,6(7)-双甲酰基四硫富富瓦烯的偶联反应。据报道制备了许多新的1,4-二硫富烯。
