A new synthetic method for triazatruxenes from indoles is developed using N-bromosuccinimide (NBS) as a user-friendly reagent. Major reaction parameters including the amount of NBS, substrate concentration, temperature, addition rate and addition method are investigated. Additional experiments are also conducted in order to gain access toward the reaction mechanism. Compared to the use of Br2 in the

When indole reacted with titanium (III)- or iron (II)-hydrogen peroxide systems, the products varied widely, depending on the pH of the reaction solutions. Under acidic conditions, indole gave rise to oxindole, 2, 3'-biindole and a novel indole trimer, diindolo-[2, 3-a : 2', 3'-c] carbazole. Under neutral conditions, indole was converted to oxindole, hydroxyindoles and 3, 3'-biindole. The structure of the trimer was determined by X-ray diffraction analysis of its monoacetyl derivative. A possible mechanism for the formation of the products is proposed.
当吲哚与钛(III)-或铁(II)-过氧化氢体系反应时,产物的差异很大,这取决于反应溶液的 pH 值。在酸性条件下,吲哚会生成氧化吲哚、2,3'-联吲哚和一种新型吲哚三聚体--二吲哚-[2,3-a : 2',3'-c] 咔唑。在中性条件下,吲哚可转化为氧化吲哚、羟基吲哚和 3,3'-联吲哚。通过对其单乙酰衍生物进行 X 射线衍射分析,确定了三聚体的结构。提出了产物形成的可能机制。
