N-Triarylbisenamines have been efficiently formed and isolated for the first time. The synthesis is based on an unprecedented gold(I)-catalyzed double intermolecular hydroamination between N-arylamines and aryl alkynes. This reaction constitutes a new example of the intriguing behavior of gold as catalyst in organic synthesis. The reactivity of these bisenamines for three different reactions, leading to potentially
α,α',N-三芳基双烯胺已被首次有效地形成和分离。该合成基于空前的
金(I)催化的N-芳基胺和芳基
炔烃之间的双分子间加
氢胺化反应。该反应构成了
金在有机合成中作为催化剂的引人入胜的行为的新例子。还显示了这些比森胺对三种不同反应的反应性,从而导致可能有用的中间体。尤其是,受阻的
氮杂双环[3.2.0]具有出色的UVA和UVB吸收特性,是通过在预料之外的机理中向
丙酸酯中添加三芳基双烯胺而获得的。
