Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Heterocycles called An unusual photochemical reaction of indene with furan and thiophene derivatives, Author is D’Auria, Maurizio; De Mico, Antonella; D’Onofrio, Franco, which mentions a compound: 2689-65-8, SMILESS is IC1=CC=C(O1)C=O, Molecular C5H3IO2, SDS of cas: 2689-65-8.
Photochem. substitution of iododfurans or iodothiophenes by indene gave 2-indenylfurans or -thiophenes. E.g., irradiation of 5-iodofuran-2-carboxaldehyde in MeCN in the presence of indene gave the substitution product I.
This literature about this compound(2689-65-8)SDS of cas: 2689-65-8has given us a lot of inspiration, and I hope that the research on this compound(5-Iodo-2-furaldehyde) can be further advanced. Maybe we can get more compounds in a similar way.
