摘要
经过重氮化、偶合、还原反应，合成了７个不同结构的苯并三唑类紫外线吸收剂。改进了还原反应条件，讨论了还原反应机理，分离出中间产物，并用红外光谱、质谱、核磁共振等方法确证了结构。讨论了紫外吸收和吸收剂结构间的关系。
Seven UV absorbers of benzotriazol structure were prepared by diazotisation, coupling and reduction. Reaction conditions were modified and reaction mechanism was studied. The intermediate compounds of reduction were isolated and identified by IR, MS and H NMR . The relationship between the UV absorption and structure was also explained.
