It is of great research value to develop an efficient and stable catalyst that can achieve the oxidation alkenes obtain epoxides, which serve as a multifunctional intermediate with important commercial value. Based on this, three-dimensional (3D) supramolecular framework H[CuI(H3bdcbpy)2(Mo12O38)(H2O)] (1, H4bdcbpy·2Cl = N,N'-bis(3,5-dicarboxybenzyl-4,4'-bipyridine·dichloride) was obtained from carboxylate-functionalized 1D coordination polymers, were derived unusual in situ [Mo12O38]4- cluster Cu-electron-deficient carboxylate complex units. The catalytic performance 1 epoxidation using TBHP examined, revealing its remarkable efficiency conversion cis-cyclooctene, high rate 99% outstanding selectivity 100%. Complex exhibited higher activity than unmodified H4bdcbpy·2Cl, CuCl2·2H2O, Na2MoO4·2H2O, well most previously reported polyoxometalate (POM)-based metal-organic complexes (POMOCs). Moreover, reaction kinetics mechanism explored free radical trapping experiments control experiments. stability also investigated.
