| Aniline is a very important amine substance.It is a common intermediate in the dye industry.It is also used in the manufacture of medicines,perfumes,paints,etc.Efficient and convenient catalysis of the coupling reaction of aniline is the focus and difficulty of organic chemistry.Actively exploring a catalyst that can be used to catalyze the coupling of aniline is also an urgent need for current organic synthesis.Metal catalysts are currently one of the most concerned catalysts.Organometallic complexes are the most prominent.In recent years,metal organic catalysts have made significant progress in coupling reactions.However,due to their cumbersome synthesis steps,they are not environmentally friendly.Series of problems have also become its drawbacks.Because of its unique structure,the polyoxometalate can be regarded as an electronic container,so it has excellent catalytic performance.Polyoxometalates have attracted more and more attention in the field of catalysis,while Lindqvist-type hexamolybdates with simple structure and small molecular weight have been reported in the field of catalysis.This site mainly explores the application of Lindqvist-type hexamolybdate in the aniline coupling reaction,which is specifically divided into the following two parts:（1）Catalyzed by Lindqvist-type hexamolybdate([N（C4H9）4]2[Mo6O19])Research on the synthesis of azobenzene and azobenzene oxide from aniline,using aniline as the template substrate,to explore the optimal reaction conditions for the synthesis of azobenzene and azobenzene oxide,and then to expand the substrate and explore the reaction Reaction mechanism;（2）Study on the synthesis of N-benzylaniline with Lindqvist type hexamolybdate([N（C4H9）4]2[Mo6O19])catalyzed by aniline and benzaldehyde,using aniline and benzaldehyde as template substrates,Explore the optimal reaction conditions for the synthesis of N-benzylaniline,and then expand the substrate with the optimal reaction conditions. |
