O-Arylation of Iodophenols with 2-Fluorobenzaldehyde Under Microwave Conditions
The arylation of 4-iodo-, 2-iodo- and 3-iodophenols with 2-fluorobenzaldehyde may be carried out in the presence
of K2CO3 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.
