Description :
2 -Hydroxy- 5- bromo acetophenone, 2-hydroxy- 3,5- dibromo acetophenone and 2 -
hydroxy-3-nitro-5-bromo acetophenone in glacial acetic acid at its boiling point treated
with ICl offords ω-iodo-2-hydroxy-5-bromo acetophenone (Ia) , ω- iodo-2-hydroxy-3,5-
dibromo acetophenone (Ib) and ω- iodo-2-hydroxy-3-nitro-5-bromo acetophenone (Ic)
condensed with substituted benzaldehyde in 40% NaOH gives aurones (IIa-l).The
structure of aurones where confirmed by chemical and spectral data.
