Abstract When we used 2-ferrocenethynylaniline (1a) as reactant and NaAuCl4·2H2O (5%) as catalyst to prepare 2-ferrocenylindole (2a), we were surprised to find that 3,3′-ferrocenylbiindole (3a) was obtained simultaneously. 3a was characterized by elemental analysis, FT-IR, MS, NMR, and X-ray single crystal diffraction. The reactant substitution reaction, in-situ HNMR, XPS, EPR characterization, and
摘要 当我们以 2-
二茂铁基
苯胺 (1a) 为反应物和 NaAuCl4·2H2O (5%) 为催化剂制备 2-
二茂铁基
吲哚 (2a) 时,我们惊讶地发现同时获得了 3,3'-
二茂铁基二
吲哚 (3a)。通过元素分析、FT-IR、MS、NMR和X射线单晶衍射表征了3a。进行了反应物取代反应、原位 HNMR、XPS、EPR 表征和计算,以解释为什么在一锅中获得 3a。结果表明,氢过氧自由基在该反应中起关键作用,诱导了 3a 的合成。图形概要
