Supported copper on a diamide-diacid-bridged PMO: an efficient hybrid catalyst for the cascade oxidation of benzyl alcohols/Knoevenagel condensation was written by Valiey, Ehsan;Dekamin, Mohammad G.. And the article was included in RSC Advances in 2022.Name: (2,4-Dichlorophenyl)methanol This article mentions the following:
In this study, a novel periodic mesoporous organosilica (PMO) containing diamide-diacid bridges was conveniently prepared using ethylenediaminetetraacetic dianhydride to support Cu(II) species and affording supramol. Cu@EDTAD-PMO nanoparticles efficiently. The stabilized Cu(II) nanoparticles inside the mesochannels of the new PMO provided appropriate sites for selective oxidation of different benzyl alcs. RCH2OH (R = Ph, 2-chlorophenyl, 4-methylphenyl, pyridin-2-yl, etc.) to their corresponding benzaldehydes RCHO and subsequent Knoevenagel condensation with malononitrile. Therefore, Cu@EDTAD-PMO can be considered as a multifunctional heterogeneous catalyst, which is prepared easily through a green procedure and demonstrates appropriate stability with almost no leaching of the Cu(II) nanoparticles into the reaction medium, and easy recovery through simple filtration. The recycled Cu@EDTAD-PMO was reused up to five times without significant loss of its catalytic activity. In the experiment, the researchers used many compounds, for example, (2,4-Dichlorophenyl)methanol (cas: 1777-82-8Name: (2,4-Dichlorophenyl)methanol).
(2,4-Dichlorophenyl)methanol (cas: 1777-82-8) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Name: (2,4-Dichlorophenyl)methanol
