synthetic route for the preparation of a series of functionalized mixed thiophene/furan oligomers is described. This method, involving a Mn(OAc)3-mediated oxidative addition of β-thienyl-β-keto esters (=β-oxothiophenepropanoates) to methyl 3-thienylprop-2-enoates, allows the construction of highly functionalized heteropolyaromatic oligomers possessing various chain lengths (Schemes 2, 4, and 5). Moreover
描述了一种制备一系列功能化混合噻吩/呋喃低聚物的新颖且简单的合成路线。该方法涉及 Mn(OAc)3 介导的 β-噻吩基-β-酮酯(=β-氧代噻吩丙酸酯)与 3-噻吩基丙-2-烯酸甲酯的氧化加成,允许构建具有各种链的高度官能化的杂多芳族低聚物长度(方案 2、4 和 5)。此外,附加在呋喃环上的羰基官能团的直接转化导致了可溶于水的导电聚合物的多羧酸前体(方案 6)。
