摘要在钯的一锅催化下，二溴甲烷与溴噻吩衍生物发生Suzuki-Miyaura交叉偶联反应，实现了多种二硫代甲烷衍生物的合成。环戊二硫吩类化合物在材料科学中具有很好的应用前景，且产率较高。原位生成不稳定的亚硫基甲基硼酸酯是该反应的关键步骤。
Abstract The one-pot palladium-catalyzed Suzuki–Miyaura cross-coupling reaction of a diborylmethane with bromothiophene derivatives realized the synthesis of various dithienylmethane derivatives. Cyclopentadithiophenes, which are promising compounds in material science, can be obtained in good yields. The in situ generation of an unstable thienylmethylboronate is a key step for the present reaction.
