A 1,10-phenanthroline-ligated cationic silver complex allows the intramolecular chloroamination of allenes with N-chlorosuccinimide using 2,6-lutidine as a base. This process proceeds under mild conditions and can tolerate a variety of functional groups. The chloroamination products are useful synthetic intermediates and can be easily transformed into functionalized 3-pyrroline and pyrrole derivatives
与1,10-菲咯啉连接的阳离子银络合物允许使用2,6-二甲基吡啶作为碱,用N-氯代琥珀酰亚胺进行烯丙基的分子内氯胺化。该过程在温和的条件下进行,可以耐受各种官能团。氯胺化产物是有用的合成中间体,并且可以容易地转化为官能化的3-吡咯啉和吡咯衍生物。
