Abstract:


The arylation of 4-iodo-, 2-iodo- and 3-iodophenols with 2-fluorobenzaldehyde may be carried out in the presence of K<sub>2</sub>CO<sub>3</sub> in DMF as the solvent under microwave conditions. The arylation of 4-iodophenole was promoted by the use of triethylbenzylammonium chloride (TEBAC) as the phase transfer catalyst. In the other model reactions, the use of TEBAC was harmful. By-products formed by isomerization and disproportionation were also detected.

Keywords:

2-Flourobenzaldehyde, Iodophenols, Arylation, Microwave, Phase transfer catalysis.
