A catalyst is for use in a reaction using an oxygen-atom-containing reactant arid includes a nitrogen-containing heterocyclic compound of the following formula (1):
wherein each of R1 and R2 is, identical to or different from each other, a hydrogen atom, a halogen atom, an alkyl group, a haloalkyl group, an aryl group, a cycloalkyl group, a hydroxyl group, an alkoxy group, a carboxyl group, an alkoxycarbonyl group, or an acyl group, and R1 and R2 may be combined to form a double bond or to form an aromatic or non-aromatic ring with the adjacent two carbon atoms, where one or two of heterocyclic ring containing three nitrogen atoms indicated in the formula may be further formed on the R1 or R2, or on the double bond or aromatic or non-aromatic ring formed by R1 and R2; X is an oxygen atom or a hydroxyl group; and Y is a single bond, a methylene group, or a carbonyl group. This catalyst can introduce an oxygen-atom-containing group into an organic substrate under mild conditions.
一种催化剂用于使用含氧原子的反应物的反应,包括下式(1)的含氮杂环化合物:
其中 R1 和 R2 各自是相同或不同的氢原子、卤素原子、烷基、卤代烷基、芳基、环烷基、羟基、烷氧基、羧基、烷氧羰基或酰基、且 R1 和 R2 可结合形成双键,或与相邻的两个碳原子形成芳香环或非芳香环,其中 R1 或 R2 上,或 R1 和 R2 形成的双键或芳香环或非芳香环上可进一步形成式中所示的含有三个氮原子的杂环中的一个或两个;X 是氧原子或羟基;Y 是单键、亚甲基或羰基。这种催化剂可以在温和的条件下将含氧原子的基团引入有机底物中。
