The copper ferrite supported reduced graphene oxide (CuFe2O4@rGO) synthesis by solvothermal process has been reported. The prepared CuFe2O4@rGO catalyst was used for C-O and C-N cross coupling reactions. The activity of the catalyst was compared with com. Cu2O, CuO and CuFe2O4 for C-O cross coupling of iodobenzene with phenol. The CuFe2O4@rGO was the best catalyst with 97% conversion towards iodobenzene at 100 °C under ligand free condition which is otherwise normally used. The virgin and five times reused CuFe2O4@rGO catalyst was characterized by XRD, SEM, FTIR, TEM, N2-adsorption desorption isotherm, XPS and TGA anal. The effect of solvent, nature of base, speed of agitation, mole ratio, catalyst loading and temperature were studied for phenol and iodobenzene reaction and its activity was further explored in N-arylation of indole with iodobenzene. The best conversion and yield were achieved at 100 °C at 1×10-3 g/cm3 catalyst loading. Notably, CuFe2O4@rGO was reusable without any loss of catalytic activity for five recycles. Reaction mechanism and kinetics are also presented. The overall process is novel and green. In the experiment, the researchers used many compounds, for example, 1-(4-(4-Methoxyphenoxy)phenyl)ethanone (cas: 54916-28-8Category: ethers-buliding-blocks).
1-(4-(4-Methoxyphenoxy)phenyl)ethanone (cas: 54916-28-8) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Category: ethers-buliding-blocks
