Abstract

A facile synthesis of copper nanoparticles supported on an ordered mesoporous polymer was developed for solvent-free Sonogashira coupling reactions.

Ordered mesoporous SBA‐15 functionalized with yttrium(III) and cerium(III) complexes: Towards active heterogeneous catalysts for oxidation of sulfides and preparation of 5‐substituted 1H‐tetrazoles

“…The textural data derived from nitrogen adsorption–desorption measurements are presented in Table . With functionalization of SBA‐15 with Creatinine@M, the resulting SBA‐15@Creatinine@Y and SBA‐15@Creatinine@Ce exhibit a lower BET surface area, pore size and total pore volume, which might correspond to the occupation of the pore channels by Creatinine@Y and Creatinine@Ce …”

“…The peak intensity of (100) diffraction was decreased. Also, the (110) and (200) diffractions were absent in the patterns of these samples, indicating that the degree of ordering of mesoporous SBA‐15 was decreased with the introduction of the metal complex …”

Acyl Sonogashira Cross-Coupling: State of the Art and Application to the Synthesis of Heterocyclic Compounds

“…Analogously, Bhanage's group [64] described the preparation of Cu/CuO 2 nanoparticles via microwave irradiation and their excellent applicability to acyl Sonogashira reactions of substrates with different functional groups (NH 2 , OH, Cl, OCH 3 , CH 3 ). More recently, a mesoporous polymer-supported Cu NPs catalyst was developed [65] and applied to palladium-and solvent-free coupling of acid chloride and aryl alkynes. Similar experimental conditions were used in the acylation of aryl acetylenes with benzoyl chloride promoted by a nanosized Cu 2 O/SiO 2 egg-shell catalyst [66].…”

A highly efficient nano-sized Cu2O/SiO2egg-shell catalyst for C–C coupling reactions

“…It was found that supported copper nanoparticles efficiently catalyzed the synthesis of ynones of acyl chlorides and alkynes. 33,34 In this type of reaction, Cu 2 O nanoparticles activate phenylacetylene to form copper(I) acetylide compounds, which subsequently react with acyl chloride. 35,36 In addition, this reaction does not require any ligand and palladium source under solvent-free conditions.…”
