Four categories of sulfonic acid functionalized fiber catalysts with different surface microenvironments were synthesized by covalent grafting using polyacrylonitrile fiber (PANF) as the support. After the effect of acid structure on catalytic activity was investigated by Friedlander reaction, PANEOSF was chosen for the synthesis of quinolines and coumarin derivatives with high yields and extensive substrate scope (51 examples) in ethanol or water. The effect of electrostatic microenvironment and solvent was discussed and a “”release-catch-release-catch”” catalytic pattern was proposed accordingly. PANEOSF can be easily recycled for 20 times without any decrease of catalytic activity. In the experimental materials used by the author, we found Ethyl 3-oxopentanoate(cas: 4949-44-4Synthetic Route of C7H12O3)
Ethyl 3-oxopentanoate(cas: 4949-44-4) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Synthetic Route of C7H12O3
