The reaction course was found to be strongly dependent on the oxidant leading to the products of bis(triflamidation) or heterocyclization in the system (t-BuOCl + NaI), or amidines – the Ritter-type solvent interception halosulfamidation products – with N-bromo- or N-iodosuccinimide. The amidines were converted to imidazolines in high yield via the base-induced heterocyclization.
在各种氧化剂(t-BuOI,NBS,NIS)存在下,已经研究了三氟化物与一系列单和二烯丙基杂原子化合物的反应。发现反应过程强烈依赖于氧化剂,该氧化剂会导致系统中的双(三氟化)或杂环化产物(t-BuOCl + NaI),或am(Ritter型溶剂拦截卤代磺酰胺化产物)和N-溴-或N-碘代琥珀酰亚胺。the通过碱基诱导的杂环化以高产率转化为咪唑啉。
