Synthesis Of Nitrogenous Heterocyclic Compounds And Exploration Of Their Coordination Complexes

In recent years,the nitrogenous heterocyclic organic compounds have been widely used in medicine and pesticide due to its high absorbability,easy decoration and low toxicity.The paper mainly optimizes the synthesis process of N-methyl-N,N'-2(pyridine-2-methyl)ethylenediamine and 4-(2(1-pyrazole)methyl)pyridine,and explores the influence of the temperature,time and molar ratio of reactants on the reaction,and eventually determines the optimal preparation process of two series of the heterocyclic compounds.The complexes characterized by Spin-crossover,as a new generation of molecular switch and information original,has some meaning on development.After the process optimization of compounds,we use compounds and a part of the transition elements to get a series of new magnetic materials,with characterization of structure and study on magnetic properties according to these materials.This paper is mainly composed of five chapters.The first chapter is an introduction to the research background.The second chapter is about the preparation process of nitrogenous heterocyclic organic compounds,the preparation process of series of pyridine compounds,and the structure identification of compounds.The third chapter,as the focus of this paper,studies on the preparation process of series of pyridine compounds,controls the impact of various factors on the reaction,and confirms the optimum preparation conditions.The fourth chapter,with a pyridine compound as the center to build series of complexes,with the structure identification and property analysis.The fifth chapter is conclusion and prospect.
