This paper reports a heterogeneous magnetic impressive nickel catalyst in which Fe3O4 nanoparticles have been coated with chitosan and decorated with nickel nanoparticles (Fe3O4@CS-Ni). This catalyst has been used for direct α-alkylation of aryl ketones with substituted benzyl alcs. through borrowing hydrogen and dehydrogenation mechanism that affords the corresponding α-benzyl ketones, with good to excellent yield. The core-shell morphol. has been confirmed with different anal. techniques such as Fourier-transform IR (FT-IR), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), SEM (SEM), transmission electron microscopy (TEM), SEM mapping, energy-dispersive X-ray (EDX), inductively coupled plasma (ICP), and thermogravimetric anal. (TGA). Moreover, the catalyst could be recovered from the reaction mixture by using an external magnetic field and reused for six successive cycles without a considerable decrease in catalytic activity. In the experiment, the researchers used many compounds, for example, (4-Chlorophenyl)methanol (cas: 873-76-7Application In Synthesis of (4-Chlorophenyl)methanol).
(4-Chlorophenyl)methanol (cas: 873-76-7) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application In Synthesis of (4-Chlorophenyl)methanol
