Diiodophenols

from Wikipedia, the free encyclopedia

The diiodophenols form a group of aromatic compounds that are derived from both phenol and iodobenzene or diiodobenzenes . The structure consists of a benzene ring with an attached hydroxyl group  (-OH) and two iodine atoms  (-I) as substituents . Their different arrangement results in six constitutional isomers with the empirical formula C 6 H 4 I 2 O.
