This article investigates an efficient and eco-friendly protocol for protecting amines and alcohols as important molecules in organic chemistry, using Fe3O4@MCM-41/Zr@Piperazine as a newly reported magnetic mesoporous nanostructured catalyst. Firstly, the protection of alcohols was developed through their transformation to trimethylsilyl ethers. Then this reagent was applied for the acceleration of the acetylation of […]
The direct and indirect methods in solvent media and grinding method in a solvent-free media were used to prepare the MCM-41/ZnO and MCM-48/ZnO photocatalysts. The X-ray diffraction (XRD) patterns showed that zinc oxide nanoparticles were put into MCM-41 and MCM-48 substrates and there were ZnO crystallites as secondary phase in the extra framework of mesoporous […]
