Dative and covalent-dative postsynthetic modification of a two-fold interpenetration pillared-layer MOF for heterogeneous catalysis: A comparison of catalytic activities and reusability

• Two heterogeneous catalysts based MOF was synthesized via Postsynthetic modification.
• The catalytic activity of two catalysts was studied in the alkenes oxidation.
• Mo(VI) based MOF catalysts show good selectivity toward epoxide.
• Covalent functionalization generates reusable and robust heterogeneous catalyst.

Two MOF-supported Mo(VI) oxidation catalysts bearing N,O-chelating ligand were synthesized via dative and covalent-dative postsynthetic modifications of a two-fold interpenetration pillared-layer amine-functionalized MOF known as TMU-16-NH2. These post-functionalized catalysts were characterized by FT-IR spectroscopy, thermogravimetric analysis, ICP and X-ray powder diffraction techniques. The Mo(VI)-containing MOFs exhibit both epoxide selectivity and fully reusability for alkenes epoxidation by tert-butylhydroperoxide (TBHP).

An amine-functionalized two-fold interpenetration metal-organic framework has been modified by postsynthetic modification with molybdenum (VI) complex for selective catalytic epoxidation of alkenes.Figure optionsDownload as PowerPoint slide
