The ‘valence tautomers’ of o-iodosobenzoic acid: the case of 4-pentyl-2-iodosobenzoic acid
Abstract
Contrary to a previous report, only the closed (iodoxolone) form of 4-pentyl-2-iodosobenzoic acid (3a) can be isolated; the previously assigned open (iodoso) form (3b) is actually 4-pentanoyl-2-iodobenzoic acid.
