An improved synthesis of EDSEDT-TTF 4 and EDSEDO-TTF 5 from appropriate cross-coupling reactions involving 4,5-bis(2-cyanoethylthio)-1,3-dithiol-2-one (9) and 4,5-bis(2-cyanoethylseleno)-1,3-dithiol-2-one (11) as key intermediates is described. Moreover, a Wittig-type preparation of new selenated derivatives 6 and 7 of DMET molecule from the useful new precursor [4,5-bis(2-cyaoethylseleno)-1,3-dithiol-2-yl]triphenylphosphonium tetrafluoroborate (17) is presented.
描述了一种改进的合成方法,通过合适的交叉偶联反应,利用4,5-二(2-氰乙基硫)-1,3-二硫醇-2-酮(9)和4,5-二(2-氰乙基硒)-1,3-二硫醇-2-酮(11)作为关键中间体,合成EDSEDT-TTF 4和EDSEDO-TTF 5。此外,还展示了一种Wittig型合成方法,利用有用的新前体[4,5-二(2-氰乙基硒)-1,3-二硫醇-2-基]三苯基磷四氟硼酸盐(17),制备DMET分子的新的硒化衍生物6和7。
