In this study, palladium-based heterogeneous catalysts were successfully prepared by encapsulating the palladium diphosphine complexes into an imine-linked 2D-COF (TPB-DMTP-COF) through a one pot self-assembly approach. It not only prevents the oxidation of phosphine-based ligand during the stepwise impregnation but also suppresses the coordination of imine linkers at the COF host to the palladium guest, thus enabling highly efficient encapsulation of the active bidentate phosphine chelated palladium complex by the widely explored imine-linked COF. Besides, the dosage of diphosphine ligand (Xantphos-SO3H, L) and the ratio of palladium to L in the preparation of [Pd]@COF hybrids can be readily adjusted under such one pot procedure to satisfy the requirement of crystallinity, porosity, active sites, and CO adsorption capacity for the catalytic performance in the methoxycarbonylation of olefins. The resultant [Pd]@COF-A-0.25-0.5 provides satisfied catalytic performance for both aliphatic and aromatic olefins with total esters up to 92.1% under optimized conditions. These findings provide the basis for a novel design concept to design heterogeneous catalysts with high efficiency for reaction processes comprising the alkoxycarbonylation of olefins. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Name: Methyl heptanoate).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Name: Methyl heptanoate
