Synthesis Of Ditriazole-based NHC-Pd Complexes And Its Catalyzed Hydroamination

This paper studies the synthesis of a series of triazole carbene palladium compounds and their application in hydroamination reaction of alkyne. It can be divided into the following four parts:The first chapter introduces the progress of N-heterocyclic carbene metal organic chemistry, hydroamination and the significance of this paper.The second chapter presents a range of different triazole salts by the simple1,2,4-1H-triazole and aromatic amines as raw material. All compounds were characterized(1H NMR,13 C NMR, EA).The third chapter describes that triazole different carbene palladium compounds were synthesized in simple reaction conditions. These palladium compounds have different substituents such as aryl, alkyl and also have different chain lengths bridging.These compounds were characteried by1 H NMR,13 C NMR and EA. We have got a crystal diffraction figure of one of these compounds.In the fourth chapter, we discuss the catalysis of carbene palladium compounds in the hydroamination reaction. The catalysts have achieved satisfactory results in the hydroamination reaction. The catalyst can be recycled several times.
