Fe3O4@SiO2‐copper sucrose xanthate as a green nanocatalyst for N‐, O‐ and S‐arylation. (7th December 2018) - Radfar, Iman
Abstract : Formation of C(sp 2 )–X bonds was carried out using a Fe3 O4 @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. Abstract : Formation of C(sp 2 )‐X bonds are carried out by Fe3 O4 @SiO2 ‐copper(I) Sucrose‐Xanthate (CSX) nanoparticles by aid of the copper(I) xanthate moiety in catalyst which was prepared from reaction between sucrose and carbon disulfide through an alkaline medium via Zeise's traditional approach. FT‐IR, XRD, VSM, SEM‐EDX, TGA and ICP tests were employed for characterization of this new‐generated nanoparticles. Three various sorts of heteroatoms, N, O, and S successfully underwent heteroatom‐arylation to produce 2° or 3° amines, ethers and thioethers, respectively.
