A dithienylethene synthon, 3,4-bis-(5-iodo-2-methylthien-3-yl)-2,5-dihydrothiophene, was prepared and used as a starting material for the preparation of several photochromic dithienylethene derivatives via Suzuki cross-coupling reactions. The dithienylethene synthon was stable once stored in the dark at room temperature.
合成了二噻烯合成子,3,4-双(5-碘-2-甲基噻吩-3-基)-2,5-二氢噻吩,并将其作为起始材料,通过铃木交叉偶联反应制备了几种光致变色二噻烯衍生物。该二噻烯合成子在室温暗处储存时稳定。
