Fe₃O₄@SiO₂‐copper sucrose xanthate as a green nanocatalyst for N‐, O‐ and S‐arylation

Abstract

Formation of C(sp2)–X bonds was carried out using a Fe3O4@SiO2‐copper(I) sucrose xanthate nanoparticle catalyst with the aid of the copper(I) xanthate moiety in the catalyst which was prepared from the reaction between sucrose and carbon disulfide through an alkaline medium via the traditional Zeise approach. Various techniques were employed for the characterization of these novel nanoparticles. Three sorts of heteroatoms, N, O and S, successfully underwent heteroatom arylation to produce secondary or tertiary amines, ethers and thioethers, respectively.

Recent Advancement of Ullmann Condensation Coupling Reaction in the Formation of Aryl-Oxygen (C-O) Bonding by Copper-Mediated Catalyst

“…In a continuous study on the preparation of new recoverable magnetic nanoparticles, Iman Radfar et al proposed a new magnetic nanoparticle functionalized sugar onto the silicon dioxide solid (Scheme 20). In that study, Fe3O4@SiO2-copper(I) sucrose xanthate provided an excellent catalytic activity in the formation of ether bond, and it can be recycled up to five times without loss of its catalytic activity [58]. rpm and only 1 × 10 −3 g/cm 3 of CuFe2O4@RGO catalyst is needed to obtain the highest yield of the products (Scheme 19).…”

Organosulphur and organoselenium compounds as emerging building blocks for catalytic systems forO-arylation of phenols, a C–O coupling reaction

“…[25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] In the recent past, organosulphur and organoselenium ligands have been used to develop interesting and highly competent homogeneous, heterogeneous and nanocatalytic systems for C-O coupling reactions. [56][57][58][59][60][61][62][63][64][65][66][67] However, such ligands have not been so much explored for this purpose as the ligands that have oxygen, nitrogen or phosphorous. This is probably because there is a belief in the scientific community that most often the transition metal catalysts are poisoned by sulphur and selenium.…”

L‐lysine‐Pd Complex Supported on Fe3O4MNPs: a novel recoverable magnetic nanocatalyst for Suzuki C‐C Cross‐Coupling reaction

“…This magnetization value is less than the uncoated Fe 3 O 4 MNPs due to the coated shell. [122] In order to evaluate the morphology and particle size of the Fe 3 O 4 @L-lysine-Pd hybrid material, scanning electron microscopy (SEM) was used (Figure 8). On the basis of SEM images, the catalytic particles in the lysine-Pd sample has a spherical shape.…”
