Abstract
Disclosed is an application of an ionic iron (III) complex as a catalyst in preparation of a benzylamine compound, that is, an ionic iron (III) complex having a molecular formula of [(RNCHCHNR)CH][FeBr] (R is tert-butyl) and containing 1,3-di-tert-butyl imidazolium cation is used as a catalyst, di-tert-butyl peroxide is used as an oxidizing agent, and a benzylamine compound is synthesized by oxidation reaction of a toluene/ethylbenzene compound with an aromatic amine. The present invention has a wide application range, and is applicable not only to a toluene compound containing a benzylic primary carbon-hydrogen bond but also to an ethylbenzene compound containing a benzyl secondary carbon-hydrogen bond. This is the first example of the preparation of a benzylamine compound by oxidation reaction of a toluene/ethylbenzene compound and an aromatic amine by an iron-based catalyst.
