which are further extended via 4,4-bpt connectors into a noninterpenetrating 3D framework architecture. It was found that 1 can be as a heterogeneous catalyst for multiple organic reactions, such as azide-alkyne cycloaddition and Friedel–Crafts reactions with good isolated yields and good recycle runs (at least five times without substantial degradation). Additionally, 1 can promote hydrosilylation of
考虑到它们的环保特性和潜在的催化剂可回收性,使用金属-有机骨架(MOFs)作为催化剂的有机反应很有希望。一个强大的Co(II)-MOF [CO 2(大号-mac)(4,4- BPT)(H 2 O)]·3.5H 2 ö} Ñ(1)及其对映体[CO 2(d - mac)(4,4-bpt)(H 2 O)]·3.5H 2 O} n(2)(L / D -mac = L / D-苹果酸的基本形式,4,4-Hbpt = 3, 5-二(吡啶-4-基)-4 H-1,2,4-三唑)已在溶剂热条件下克级制备。结构分析表明,mac管理Co(II)离子以形成1-D链,该链通过4,4-bpt连接器进一步扩展为非互穿3D框架体系结构。发现1可以作为多种有机反应的非均相催化剂,例如叠氮化物-炔烃环加成反应和Friedel-Crafts反应,具有良好的分离收率和良好的循环运行性能(至少5次没有实质性降解)。另外,1可以
