Building a Green, Robust, and Efficient Bi-MOF Heterogeneous Catalyst for the Strecker Reaction of Ketones
[Image: see text] In this work, we present the new [Bi(14)(μ(3)-O)(9)(μ(4)-O)(2)(μ(3–)OH)(5)(3,5-DSB)(5)(H(2)O)(3)]·7H(2)O, BiPF-4 (bismuth polymeric framework—4) MOF, its microwave hydrothermal synthesis, as well as its behavior as a heterogeneous catalyst in the multicomponent organic Strecker rea...

Sumario: | [Image: see text] In this work, we present the new [Bi(14)(μ(3)-O)(9)(μ(4)-O)(2)(μ(3–)OH)(5)(3,5-DSB)(5)(H(2)O)(3)]·7H(2)O, BiPF-4 (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 BiPF-4 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. BiPF-4 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. |
