Abstract
Procedure for the preparation of unsaturated derivatives of trihydroxyacetophenone of the type of the compounds of the formula: ** (See formula) ** In which RR1 and R2 can be identical or different and represent a hydrogenoun atom, halogen announcement hydroxyl radical or radical alkoxycharacterized in that an aromatic aldehyde of formula ** (See formula) ** in which RR1 and R2 have the same significance as indicated above is added to the trihydroxyacetophenone in substantially equimolar proportions.
