Synthesis,Structure,and Functional Investigation Of The Complexes With Pyrazole Derivatives As Ligands And The Designing Nitrogen-containing Heterocyclic Compounds By Suzuki Coupling

Pyrazole and its derivatives are widely used in the fields of pesticide,medicine and antibacterial due to their high biological activities and pharmacological activity.They have some advantages in coordination chemistry,such as good planarity,larger conjugated system,stable structure,and so on.The complexes with them were studied in the fields of sensors,probe,catalysis,biochemistry and materials.At the same time,Biphenyl-containing heterocyclic compounds are also be used in those areas.And the Suzuki coupling reaction is considered as one of the most important way that synthesizing biphenyl-containing heterocyclic compounds.It is widely used in synthesizing exploration of functional materials,biological agents.In this thesis,we synthesized four biphenyl-carboxylic acid containing heterocyclic compounds through the Suzuki coupling reaction.They were characterized by IR spectroscopy,elemental analysis,1H NMR and 13 C NMR.At the same time,we used pyrzaole and its derivatives as start materials,and synthesized a series of ligands and related four complexes.All complexes were characterized by the elemental analysis,IR spectroscopy,X-ray powder diffraction and X-ray single crystal diffraction.Parts of them were investigated mimicking catalytic bromide activity...
