2-Iodophenol

2-Iodophenol is an aromatic organic compound with the formula IC₆H₄OH. It is a pale yellow solid that melts near room temperature. It undergoes a variety of coupling reactions in which the iodine substituent is replaced by a new carbon group Arene [substitution pattern|ortho] to the hydroxy group of the phenol, which can be followed by cyclization to form heterocycles.
It can be prepared by treatment of 2-chloromercuriphenol with iodine:
Direct reaction of phenol with iodine gives a mixture of 2- and 4-iodo derivatives.
