The Uses of 3-Iodophenol

3-Iodophenol is used in esterification, electrophilic aromatic substitution, alkylation, nucleophilic aromatic substitution, Mitsunobu, transition metal-catalyzed cross-coupling, acylation, and oxidation reactions.

Definition

ChEBI: 3-iodophenol is an iodophenol.

What are the applications of Application

3-Iodophenol is used in the synthesis of centrally acting H2 receptor histamine antagonists. Also used in the preparation of various cell-permeable probes for biological assays.

Synthesis

3-Iodophenol Synthesis:
1￡?Add potassium tert-butoxide (67.3 mg, 0.60 mmol, 2.0 eq.), oxime (74.5 mg, 0.60 mmol, 2.0 eq.), and 4??-bromoacetophenone (59.7 mg, 0.30 mmol, 1.0 eq.) to an oven-dry screw-cap 8mL reaction vial.
2￡?Add anhydrous DMSO (1.5 mL) to the solids a magnetic stir bar.
3￡?Close the vial and sparge the reaction mixture with N2 for 15 minutes, seal with parafilm.
4￡?Stir the reaction mixture and heat at 100??C in a metal heating block for 16 h.
5￡?Dilute the mixture with CH2Cl2 or EtOAc (20 mL), pour into a mixture of water (10mL) and brine (5 mL), acidify with 10% aq HCl (~1 mL).
6￡?Collect the organic phase and extract the aqueous phase with CH2Cl2 or EtOAc (3?á20mL).
7￡?Combine the organics, dry (MgSO4) and concentrate under reduced pressure.
8￡?Purify the crude product to give 3-Iodophenol by column chromatography (30% EtOAc in hexane).
