Definition

ChEBI: 4-iodophenol is an iodophenol.

Preparation

It is obtained from 4-Aminophenol by diazotisation and substitution.

What are the applications of Application

4-Iodophenol can be used as a building block for the synthesis of:
Hydroxybiaryls by reacting with aryl boronic acids via Pd-catalyzed Suzuki-Miyaura coupling reaction.[1][2]
Aryl substituted olefins by reacting with acrylates via Pd-catalyzed Heck reaction.[3]
Iodinated-4-aryloxymethylcoumarins [4]
Hydroxylated stilbenoids [5] and psammaplysenes A and B.[6]

Metabolism

4-Iodophenol has known human metabolites that include (2S,3S,4S,5R)-3,4,5-trihydroxy-6-(4-iodophenoxy)oxane-2-carboxylic acid.

Purification Methods

Crystallise 4-iodophenol from pet ether (b 80-100o) or distil it in vacuo. If the material has a brown or violet color, then dissolve it in CHCl3, shake it with 5% sodium thiosulfate solution until is colourless. Dry (Na2SO4), extract, evaporate and disil the residue in vacuo. [Dains & Eberly Org Synth Coll Vol II 355 1948, Beilstein 6 IV 1074.]
