Abstract A simple and novel bimetallic catalyst, an iron and magnesium complex (Fe‐Mg‐hexamethylphosphoramide (HMPA)), with dual activation was found to be an effective and promising catalyst for the Michael‐type Friedel–Crafts reactions of indoles with chalcones. This novel catalytic system has the advantages of highly efficient, mild reaction conditions and exhibits high reactivity and selectivity
摘要 一种简单而新颖的双金属催化剂,铁和镁配合物(Fe-Mg-六甲基磷酰胺(HMPA)),具有双重活化作用,被发现是吲哚与查耳酮的 Michael 型 Friedel-Crafts 反应的有效且有前景的催化剂。这种新型催化体系具有高效、反应条件温和、反应活性和选择性高的优点,使其成为合成吲哚衍生物的有用且有吸引力的方法。
