IODINATION OF 6-ARYL-2-PYRONES
Sokolovskaya, S. V.,Moldovanova, L. K.
, p. 492 - 494 (2007/10/02)
The iodination of 6-aryl-2-pyrones with iodine chloride in glacial acetic acid leads to the corresponding 3-iodo derivatives. 3-Cyano-6-phenyl-2-pyrone and 3-phenylethynyl-6-phenyl-2-pyrone were obtained by replacement of the iodo group by cyano and phenylethynyl groups.
