A substrate (e.g., a cycloalkane, a polycyclic hydrocarbon, an aromatic compound having a methyl group or methylene group adjacent to an aromatic ring) is oxidized with oxygen in the presence of an oxidation catalyst comprising an imide compound of the following formula (1) (e.g., N-hydroxyphthalimide), and a co-catalyst (except phosphovanadomolybdic acid) containing an element selected from the group consisting of Group 2A elements of the Periodic Table of Elements, transition metals (Group 3A to 7A elements, Group 8 elements, Group 1B elements and Group 2B elements of the Periodic Table of Elements) and Group 3B elements of the Periodic Table of Elements, for the formation of an oxide (e.g., a ketone, an alcohol, a carboxylic acid):
wherein R1 and R2 represent a substituent such as a hydrogen atom or a halogen atom, or R1 and R2 may together form a double bond or an aromatic or nonaromatic 5- to 12-membered ring, X is O or OH, and n is 1 to 3.
底物(如环烷烃、多环烃、与芳香环相邻的具有甲基或亚甲基的芳香族化合物)在氧化催化剂存在下被氧气氧化,氧化催化剂包括下式(1)的亚胺化合物(如:N-羟基邻苯二甲酰亚胺)和助催化剂(磷酰二钼酸除外),助催化剂含有选自元素周期表 2A 族元素组成的组的元素、N-羟基邻苯二甲酰亚胺),以及含有选自元素周期表 2A 族元素、过渡金属(元素周期表 3A 族至 7A 族元素、8 族元素、1B 族元素和 2B 族元素)和 3B 族元素组成的组的元素的助催化剂(磷钒钼酸除外),以形成氧化物(如酮、醇、羧酸):
其中 R1 和 R2 代表取代基,如氢原子或卤素原子,或 R1 和 R2 可共同形成双键或芳香族或非芳香族 5 至 12 元环,X 为 O 或 OH,n 为 1 至 3。
