In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Dipole moments of some furfural derivatives, published in 1962, which mentions a compound: 2689-65-8, mainly applied to , Reference of 5-Iodo-2-furaldehyde.
The following values of dipole moments (in D.) were determined from the dielec. data in C6H6 at 25°: furfural 3.56; 5-bromofurfural 3.37; 5-iodofurfural 3.29; 5-chiorofurfural 3.37; 5-nitrofurfural 3.46; 5-nitrofurfurylidene diacetate 4.26; the following values were found in dioxane: furfural 3.6, 5-iodofurrural 3.39. The results indicate that free rotation of the CHO group in furfural and its 5-halo derivatives is restricted and the mols. exist mainly in a conformation with the CHO-oxygen atom disposed toward the ring O atom.
From this literature《Dipole moments of some furfural derivatives》,we know some information about this compound(2689-65-8)Reference of 5-Iodo-2-furaldehyde, but this is not all information, there are many literatures related to this compound(2689-65-8).
