2-Oxo-5,6-dihydro-1,3-dithiolo[4,5-b][1,4]dithiin (4) was prepared in four steps from cheap starting materials in high overall yield. Coupling of 4 with trimethyl phosphite in toluene gave bis(ethylenedithio)tetrathiafulvalene (5; BEDT-TTF; 2,2′-bi-5,6-dihydro-1,3-dithiolo[4.5-b][1,4]dithiinylidene) in 96% yield.
2-氧基-5,6-二氢-1,3-二硫烯[4,5-b][1,4]二硫噻烷(4)通过四个步骤从廉价的起始材料中制备,整体产率很高。将4与三甲基磷酸酯在甲苯中偶联,得到双(乙烯二硫基)四硫富瓦烯(5;BEDT-TTF;2,2'-双-5,6-二氢-1,3-二硫烯[4.5-b][1,4]二硫噻烷基氮)产率为96%。
