An efficient one-pot, three-component synthesis of novel push–pull 1,3-benzodithiol-2-ylidenes, involving reaction of active methylene compounds with CS2 in the presence of NaH as the base, followed by in situ Cu-catalyzed bis-CS coupling of the resulting dithioate salts with 1-bromo-2-iodobenzenes has been reported. The methodology involves readily available starting materials and tolerates a broad
一种有效的一锅三组分合成新型推拉式 1,3-苯并二硫醇-2-亚甲基,包括在 NaH 作为碱存在下活性亚甲基化合物与 CS 2的反应,然后是原位 Cu 催化已经报道了所得二硫代盐与 1-溴-2-碘苯的双-C S 偶联。该方法涉及容易获得的起始材料,并容忍广泛的官能团。
