I found the field of Chemistry very interesting. Saw the article High-efficient synthesis of 2-imino-2H-chromenes and dihydropyrano[c]chromenes using novel and green catalyst (CaO@SiO2@AIL) published in 2021. COA of Formula: C9H10O3, Reprint Addresses Mobinikhaledi, A (corresponding author), Arak Univ, Fac Sci, Dept Chem, Arak 3815688138, Iran.; Mobinikhaledi, A (corresponding author), Arak Univ, Inst Nanosci & Nanotechnol, Arak 3815688138, Iran.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde
In this work, 1,3,5,7-tetraazaadamantan-1-ium chloride (AIL) functionalized silica-coated calcium oxide hybrid nanocatalyst (CaO@SiO2@AIL) as a novel, efficient, green and recyclable heterogeneous ionic liquid catalyst was synthesized. Catalytic activity of the CaO@SiO2@AIL hybrid nanoparticles was investigated for synthesis of the pharmaceutically valuable 2-imino-2H-chromene and dihydropyrano[c]chromene derivatives. A wide range of amines and aromatic aldehydes containing either electron-withdrawing or electron-donating substituent were examined using optimized conditions to produce the desired products. 2-Imino-2H-chromenes were synthesized under solvent-free condition, and dihydropyrano[c]chromenes were prepared in aqueous medium as green conditions within short reaction times, high yields and using easy workup procedures. Structure confirmation and surface properties of the core/shell hybrid nanoparticles were considered via Fourier transform infrared spectroscopy, X-ray powder diffraction, scanning electron microscope, energy-dispersive X-ray spectroscopy, WDS map scan, thermogravimetric and elemental analyses. This IL-supported heterogeneous nanocatalyst can be reused at least six times without considerable loss of its performance.
COA of Formula: C9H10O3. Bye, fridends, I hope you can learn more about C9H10O3, If you have any questions, you can browse other blog as well. See you lster.
