Abstract Zirconium-based metal-organic framework MOF-808 was synthesized, and sulfated with aqueous sulfuric acid. Sulfated MOF-808 was utilized as a recyclable heterogeneous catalyst for the synthesis of quinazolinones from β-ketoesters and benzamides, and for the synthesis of benzimidazoles from β-ketoesters and o-phenylenediamines in glycerol as a green solvent. The sulfated MOF-808 catalyst was more active than many heterogeneous and homogeneous catalysts. The combination of the sulfated MOF-808 and glycerol was also effective for the reaction of o-aminothiophenols with β-diketones or cyclic β-diketones to produce benzothiazoles. To our best knowledge, MOF-based catalysts were not previously utilized as heterogeneous catalyst in glycerol as green solvent.

以甘油为绿色溶剂，利用可回收硫酸化金属-有机骨架-808催化剂合成喹唑啉酮类和苯并唑类

摘要 合成了锆基金属有机骨架MOF-808，并用硫酸水溶液硫酸化。硫酸化 MOF-808 被用作可回收的非均相催化剂，用于从 β-酮酯和苯甲酰胺合成喹唑啉酮，以及在作为绿色溶剂的甘油中从 β-酮酯和邻苯二胺合成苯并咪唑。硫酸化 MOF-808 催化剂比许多非均相和均相催化剂更具活性。硫酸化 MOF-808 和甘油的组合对于邻氨基苯硫酚与 β-二酮或环状 β-二酮反应生成苯并噻唑也很有效。据我们所知，以前没有将基于 MOF 的催化剂用作甘油作为绿色溶剂的多相催化剂。
