Preparation of Cu(II)‐Containing MOF Catalyst and Application in the α, β‐Dehydrogenation of Saturated Ketones

Abstract

A 0D Cu(II)-containing metal organic framework (MOF) catalyst has been developed to promote α, β-dehydrogenation of saturated ketones in the yield of 70 %-90 % at mild conditions without extra organic ligand. The single crystal data of the Cu-MOF catalyst shows the 0D structure based on the typical dinuclear paddle-wheel shaped, comprising of a Cu(II) center and four activated N atoms (including two N-methyl-pyrrolidone and two pyridine) which can activate the hydrogen atom of the saturated ketones. The Cu(II)-containing MOF catalyst also exhibited satisfactory stability in the non-proton polar solvent and could be reused for more than five times without any significant loss of activity.

Metal–organic framework (MOF)-, covalent-organic framework (COF)-, and porous-organic polymers (POP)-catalyzed selective C–H bond activation and functionalization reactions

“…The reaction pathway was proposed based on the formation of Cu( iii )–O˙ from the reaction of Cu( ii )-oxo and t BuOOH as the key species for C–H activation (Scheme 4). 52…”

ZnFe2O4@SiO2‐ascorbic acid: Green, magnetic, and versatile catalyst for the synthesis of chromeno[2,3‐d] pyrimidine‐8‐amine and quinazoline derivatives

“…For the synthesis of N-containing heterocycle compounds, many heterogeneous catalysts based on a wide variety of solid supports such as ionic liquids, [30] molecular sieves (SBA-15 and MCM-41), [31][32][33][34] boehmite, [35] and MOF have been reported. [36][37][38] Among nitrogencontaining heterocyclic systems, chromeno derivatives have attracted the organic chemist's attention due to their wide biological activities, such as antiviral, [39] antitumor, [40] antimicrobial, [41] antibacterial, [42] and pharmacological properties. [43] Quinazolines are nitrogen-containing aromatic compounds showing a wide range of biological and pharmacological activities.…”
