In this study, a new BiPF-4 material and its synthesis and catalytic activity were presented. The 2D layers of BiPF-4, formed by Bi7 polyhedra, provide numerous active sites for Lewis acid catalysis. The material exhibits excellent heterogeneous catalytic activity in the multicomponent Strecker reaction.
In this work, we present the new[Bi14(mu 3-O)9(mu 4-O)2(mu 3-OH)5(3,5-DSB)5(H2O)3]middot7H2O,BiPF-4(bismuth polymeric frame-work???4) MOF, its microwave hydrothermal synthesis, as well as its behavior as aheterogeneous catalyst in the multicomponent organic Strecker reaction. TheBiPF-4material shows a three-dimensional (3D) framework formed by peculiarinorganic oxo-hydroxo-bismutate layers connected among them through the 3,5-dsb (3,5-disulfobenzoic acid) linker. These two-dimensional (2D) layers, built byjunctions of Bi7 polyhedra SBU, provide the material of many Lewis acid catalyticsites because of the mixing in the metal coordination number.BiPF-4is a highlyrobust, green, and stable material that demonstrates an excellent heterogeneouscatalytic activity in the multicomponent Strecker reaction of ketones carried outin one-pot synthesis, bringing a reliable platform of novel green materials basedon nontoxic and abundant metal sources such as bismuth.
