Synthesis and modification of light-sensitive 3-acyl-2-hetarylchromones containing bromomethyl group in the acyl fragment

A synthesis of photosensitive 3-acyl-2-hetarylchromones containing bromomethyl group in the 3-aroyl fragment and their further modification by the reactions with N-, S- and O-nucleophiles are described. A dependence of spectral properties from the structure of compounds was studied.
