A catalyst of the invention includes an imide compound having a N-substituted cyclic imide skeleton represented by following Formula (I):
wherein R is a hydroxyl-protecting group. Preferred R is a hydrolyzable protecting group. R may be a group obtained from an acid by eliminating an OH group therefrom. Such acids include, for example, carboxylic acids, sulfonic acids, carbonic acid, carbamic acid, sulfuric acid, nitric acid, phosphoric acids and boric acids. The catalyst may include the imide compound and a metallic compound in combination. In the presence of the catalyst, (A) a compound capable of forming a radical is allowed to react with (B) a radical scavenging compound and thereby yields an addition or substitution reaction product of the compound (A) and the compound (B) or a derivative thereof. This catalyst can produce an organic compound with a high selectivity in a high yield as a result of, for example, an addition or substitution reaction under mild conditions.
本发明的催化剂包括一种亚胺化合物,其具有由下式(I)表示的 N-取代环状亚胺骨架:
其中 R 是羟基保护基团。首选 R 是可水解保护基团。R 可以是从酸中除去 OH 基团而得到的基团。此类酸包括羧酸、磺酸、碳酸、氨基甲酸、硫酸、硝酸、磷酸和硼酸等。催化剂可包括亚胺化合物和金属化合物的组合。在催化剂存在的情况下,(A) 可形成自由基的化合物可与 (B) 自由基清除化合物发生反应,从而产生化合物 (A) 与化合物 (B) 或其衍生物的加成或取代反应产物。这种催化剂可以在温和的条件下,通过加成或取代反应等,生产出具有高选择性和高产率的有机化合物。
