Solid supported Ru(0) nanoparticles: an efficient ligand-free heterogeneous catalyst for aerobic oxidation of benzylic and allylic alcohol to carbonyl

Copper Nanoparticles on Controlled Pore Glass and TEMPO for the Aerobic Oxidation of Alcohols

“…Also, the reaction conditions (temperature, reaction time and catalyst loading) used for the oxidation reactions involving the Cu‐AmP‐CPG/TEMPO system are competitive with those of other benchmark heterogeneous catalysts ,,,. Additionally, the Cu‐AmP‐CPG was shown to operate efficiently under solvent‐free conditions, unlike some other reported heterogeneous protocols ,,,,,,,–. It is also important to emphasize that there also exist metal‐free protocols based on nitric acid‐assisted oxidation systems and TEMPO, which are also attractive systems for carrying out the oxidation of alcohols.…”

An Efficient Partial Reduction of α,β‐Unsaturated Esters Using DIBAL‐H in Flow

“…1 (E)-5-Phenyl-2-pentenol (3a): [24] Colorless oil. 1 (E)-Cinnamaldehyde (1d): [25] (E)-3-(4-Bromophenyl)-2-propenal (1e): [26] (E)-3-(4-Methoxyphenyl)-2-propenal (1f): [27] (E)-2,4-Dinitrophenylhydrazone of Benzaldehyde (1g): [28] Collection time for the aldehyde: 1 min; yellow solid (208.0 mg, 81 %, as a hydrazone), m.p. 228-229°C.…”

Synthesis of 1‐aminoalkyl‐2‐naphthols derivatives using an engineered copper‐based nanomagnetic catalyst (Fe3O4@CQD@Si (OEt)(CH2)3NH@CC@N3@phenylacetylene@Cu)

“…[20] In recent years, nanomaterials have been used as a solid support material for the design of benign environmental heterogeneous catalysts. [21][22][23] A variety of methods have been developed to synthesize magnetite nanoparticles of various shapes, sizes, and compositions, but their successful applications are highly dependent on the stability conditions of these particles. [24,25] MNPs have a high affinity to agglomeration, and therefore, suitable protective materials have been investigated for their stabilization.…”
