Description
技术领域
本发明属于精细化工技术领域,具体涉及一种8-氨基喹啉(AQ)衍生物为双齿配体的四配位N,N-螯合二芳基硼酸酯(AQDAB)的制备方法。
背景技术
四配位N,N-螯合二芳基硼酸酯是一种重要的精细化工中间体,在染料、材料、光催化、有机太阳能行业中有非常广泛的应用。例如,四配位N,N-螯合二芳基硼酸酯BODIPY衍生物具有良好的光化学稳定性和优异的光电学性能,可用于制造染料,光电材料、荧光探针等诸多领域。近来,也有课题组将这类化合物用作光催化反应中的催化剂。因此,研究新型四配位N,N-螯合二芳基硼酸酯的合成和修饰方法具有重要意义和实际应用价值。目前该类化合物的合成仍然受到以下两方面的限制:(1)已报道的四配位N,N-螯合二芳基硼酸酯的合成中多数以二吡咯结构作为配体骨架结构,得到的多为四配位二吡咯硼酸酯,也就是常见的BODIPY类化合物,但该类骨架的合成和修饰一般需要多步反应才可完成,整体合成效率不高;(2)在合成N,N-螯合二芳基硼酸酯的过程中,引入芳基的步骤多需要使用芳基金属试剂(如格式试剂、锂试剂、锌试剂)才可以完成,但该类试剂的强碱性和亲核性,对反应条件要求更加苛刻,官能团兼容性较差,一些常见的官能团,如酯基、醛羰基、酰胺基团均不能与该反应条件兼容。因此,开发一种新型的四配位N,N-螯合硼酸酯类化合物,并实现其快速高效的合成,可以降低该类化合物的合成成本,实验操作难度,扩展该类化合物的多样性,为其更广泛的应用提供物质基础。
