In this work, we present the new , (bismuth polymeric framework─4) MOF, its microwave hydrothermal synthesis, as well as its behavior as a heterogeneous catalyst in the multicomponent organic Strecker reaction. The material shows a three-dimensional (3D) framework formed by peculiar inorganic oxo-hydroxo-bismutate layers connected among them through the 3,5-dsb (3,5-disulfobenzoic acid) linker. These two-dimensional (2D) layers, built by junctions of Bi7 polyhedra SBU, provide the material of many Lewis acid catalytic sites because of the mixing in the metal coordination number. is a highly robust, green, and stable material that demonstrates an excellent heterogeneous catalytic activity in the multicomponent Strecker reaction of ketones carried out in one-pot synthesis, bringing a reliable platform of novel green materials based on nontoxic and abundant metal sources such as bismuth.
在这项工作中,我们展示了新型的(铋聚合物骨架─4)金属有机框架材料、其微波水热合成方法,以及它作为多组分有机斯特雷克反应中的非均相催化剂的性能。该材料呈现出一种三维(3D)框架结构,由特殊的无机氧代-氢氧根-铋酸盐层通过3,5-dsb(3,5-二磺酸苯甲酸)连接体相互连接而成。这些二维(2D)层由Bi7多面体次级构筑单元连接而成,由于金属配位数的混合,为材料提供了许多路易斯酸催化位点。该材料是一种高度稳健、绿色且稳定的材料,在一锅法合成中进行的酮的多组分斯特雷克反应中表现出优异的非均相催化活性,基于铋等无毒且丰富的金属源,提供了一个可靠的新型绿色材料平台。
