Solvent-free and melt aerobic oxidation of benzyl alcohols using Pd/Cu₂(BDC)₂DABCO–MOF prepared by one-step and through reduction by dimethylformamide

Abstract

In this paper we report an efficient method for the aerobic oxidation of benzyl alcohols to aldehydes by supported palladium nanoparticles in nanoporous metal–organic framework Cu2(BDC)2(DABCO) that Pd(ii) in MOF reduced without using any external reducing agent.

Cu2O nanoparticles anchored on carbon for the efficient removal of propofol from operating room wastewater via peroxymonosulfate activation: efficiency, mechanism, and pathway

“…MOFs and their derivatives have received extensive attention from researchers for their outstanding performance in various applications, such as sensing adsorption, photocatalysis, drug delivery and energy storage. 21,[29][30][31] Meanwhile, due to the changeable chemical composition, large specic surface area, and controllable pore size, the MOFs derived heterostructure is an ideal activator for PMS. [32][33][34][35] Herein, a reported Cu-TCPP nanosheet was subjected to produce a heterostructure catalyst that could efficiently activate PMS in the degradation of propofol.…”

Cu-MOF: an efficient heterogeneous catalyst for the synthesis of symmetric anhydrides via the C–H bond activation of aldehydes

“…So, according to what is mentioned above and in continuation of our interest in exploring the role of MOFs as efficient heterogeneous catalysts in organic synthesis and oxidative coupling reactions, [35][36][37] herein, we report the rst application of Cu-MOFs as efficient heterogeneous catalysts for the synthesis of symmetric carboxylic anhydrides 2 via the C-H activation of aldehydes 1 using TBHP as an oxidizing agent (Scheme 2). Good to excellent yields, easy work-up of the catalyst, reusability, and minimal reaction time are some of the benecial features of this reaction.…”

“…Recycled Cu 2 (BDC) 2 DABCO aer 5 runs maintained its crystallinity based on PXRD (Fig. 3), but a slight degradation of the structure and hydrolysis reaction 44,45 could possibly justify the presence of the peaks at higher values of 2q (30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40), which probably indicates the presence of Cu(OH) 2 or CuO, 46 which are direct products of this reaction. In fact, under TBHP (70%) Scheme 3 The proposed mechanism for the synthesis of symmetric carboxylic anhydrides via C-H activation.…”

Metal-Organic Frameworks: Synthetic Methods and Potential Applications

“…The aerobic oxidation of alcohols to aldehydes or ketones requires the presence of noble metals inside the pores of the MOF or attachment to the modified ligands. Palladium and gold nanoparticles introduced into the nanoporous MOF are used for selective aerobic oxidation [ 171 , 172 ]. Cu-based MOFs are usually used as catalysts for 1,3-dipolar cycloaddition reactions, which is the formation of five-membered ring compounds [ 173 , 174 ].…”
