Furans are organic compounds with a five-membered ring consisting of four carbon atoms and one oxygen atom. The ring’s planar structure generates a circular “ring current” due to its six “pi electrons,” satisfying Huckel’s law. Furan synthesis methods include the Paal-Knorr and Feist-Benary syntheses, and furans are important starting materials for chemical synthesis, with tetrahydrofurans […]
