3-diiminoisoindolines and their related compounds from aromatic or heteroaromatic imidates and carbodiimides are reported via C–H bond activation. This reaction is the first example of a transition-metal-catalyzed insertion of carbodiimides into an aromatic or heteroaromatic C–H bond and a novel method for synthesizing 1,3-diiminoisoindolines and their related compounds. Unsymmetrical 1,3-diiminoisoindolines
据报道,由C或杂芳族酰亚胺和碳二亚胺通过C键活化activation催化的1,3-二亚氨基异吲哚啉及其相关化合物的synthesis催化合成。该反应是过渡金属催化的碳二亚胺插入芳族或杂芳族CH键的第一个例子,也是合成1,3-二亚氨基二氢吲哚及其相关化合物的新方法。使用这种方法很容易获得不对称的1,3-二亚氨基异吲哚啉。使用多种底物,反应以良好至优异的产率进行。
