Copper supported silica-based nanocatalysts for CuAAC and cross-coupling reactions

Abstract

Copper nanoparticles supported silica (CuNPs-SiO2) have been explored as sustainable catalysts for various catalytic performances of Huisgen 1,3-dipolar cycloaddition (click reaction), carbon-sulfur (CS), carbon-nitrogen (CN), and carbon-oxygen (CO) coupling reactions....

Copper-Catalyzed Reactions of Aryl Halides with N-Nucleophiles and Their Possible Application for Degradation of Halogenated Aromatic Contaminants

“…Cu-pyridine complex bound on a mesoporous silica SBA-15 surface through melamine connection was proved as an effective and simply recyclable catalyst for arylation of different primary and secondary amines using chlorobenzene in DMF/Et 3 N on air at 60 • C (Scheme 36 and Figure 9) [114,115]. A comprehensive review dealing with silica supported recyclable Cu-based catalysts is provided by Veerakumar et al [116].…”

“…Facile arylation of anilines, benzylamine and several N-heterocycles catalyzed by CuI/py on SBA-15 supported catalyst [114]. A comprehensive review dealing with silica supported recyclable Cu-based catalysts is provided by Veerakumar et al [116].…”

“…Nitrogen-rich copolymeric microsheets with molar ratio C/N = 1/2 were prepared through nucleophilic substitution of cyanuric chloride with melamine in pyridine/DMF for supporting and stabilizing Cu 0 nanoparticles. These were prepared by impregnation A comprehensive review dealing with silica supported recyclable Cu-based catalysts is provided by Veerakumar et al [116].…”

Optimized synthesis of functional organosilicon monomers and polymers exploiting new types of CuAAC recoverable heterogeneous catalysts

“…26,27 The discovery and development of the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction in the last 20 years [28][29][30][31][32] has led to the rapid development of chemistry from medical applications and the synthesis of simple molecules to the creation of complex polymeric and supramolecular structures, [33][34][35][36][37][38] including organosilicon chemistry. [39][40][41][42][43][44][45] The culmination of any chemical, and especially a "click" process, which opens up its industrial prospects, is, of course, its efficient implementation under heterogeneous conditions, which greatly facilitates the isolation of the final reaction product and allows the reuse of the catalyst, 46,47 and such processes are actively being developed and studied for the CuAAC reaction in its various applications, 31,[48][49][50][51][52] however, they are still completely absent in the chemistry of creating organosilicon molecules and practically absent in polymer chemistry.…”
