A Pd(II) Magnetically Retrievable Catalyst for Hiyama Reaction: Functionalization of Magnetic Mesoporous Silica via Click Reaction
نویسندگان
چکیده
A nitrogen ligand, i.e. 1,3-di-(o-aminophenoxy)-2-propyl propargyl ether (DPPE), has been synthesized and characterized. Magnetic mesoporous silica composite (MNP@SiO2-SBA) was obtained via embedding magnetite nano-particles (MNPs) between SBA-15 channels. DPPE palladium dichloride (MNP@SiO2-SBA-DPPE-Pd(II)) then prepared click chemistry fully The Hiyama reaction conditions including solvent, amount of catalyst, base temperature were optimized for the catalyst. activity recyclability supported magnetic Pd(II) catalyst evaluated under optimal conditions. easily separated magnetically, reused in five runs sequentially, no significant loss observed.

Pseudomorphic Reaction: A New Approach to Produce Bulk Mesoporous Silica as Catalyst Support in Methane Reforming
Pseudomorphism is known as a suitable technique for producing mesoscale pore in silica powders keeping their original morphologies. Herein, silica discs with several millimeter dimensions have been prepared using the same method. This method has been utilized through application of pseudomorphism reaction of preshaped bodies by immersion in a solution containing surfactant and swelling re...
متن کاملHighly loaded and thermally stable Cu-containing mesoporous silica-active catalyst for the NO + CO reaction.
We report the synthesis of a highly loaded and thermally stable Cu-containing mesoporous silica, which was developed by making use of poly(acrylic acid) (Pac) assembled with surfactant (C(16)TAB), as template. On this backbone, TEOS and Cu(II) hydrolysis takes place leading to the development of the final mesostructure. Poly(acrylic acid) is used not only as a micelle structural component but a...
متن کاملThe Diels-Alder reaction of C60 and cyclopentadiene in mesoporous silica as a reaction medium.
As a new organic reaction medium, a periodic mesoporous inorganic material was found to function as a "solid solvent" in a Diels-Alder reaction of C(60) with cyclopentadiene. This finding was supported by a concentration effect and a kinetic study of the reaction.
متن کاملSuperstructures of fluorescent cyclodextrin via click-reaction
Mono-(6-azido-6-deoxy)-β-cyclodextrin (CD) was covalently attached to an alkyne-modified 5-methyl-2-(pyridin-2-yl)thiazol-4-ol yielding a fluorophore containing CD in a click-type reaction. Intermolecular complexes were formed by poly(host-guest)-interactions. The supramolecular structures were characterized by (1)H NMR-ROESY spectroscopy, dynamic light scattering, UV-vis spectroscopy, fluoresc...

A magnetic nanoparticle conjugated mesoporous nanocatalyst (Fe(3)O(4)@mesoporous SBA-15) with a high surface area has been synthesized by chemical conjugation of magnetite (Fe(3)O(4)) nanoparticles with functionalized mesoporous SBA-15. Functionalized mesoporous SBA-15 containing surface carboxyl and amino groups was synthesized via the thiol-ene click reaction of cysteine hydrochloride and vin...
