Abstract
The reaction of 2-hydroxyacetophenones with trichloroacetyl chloride in the presence
of pyridine at -30 °C followed by treatment of the reaction mixture with potassium
tert -butylate affords 2-hydroxy-2-trichloromethylchroman-4-ones. Dehydration then provides
the 2-trichloromethyl-chromones.
Key words
condensation - 2-hydroxyacetophenones - 2-hydroxy-2-trichloromethylchroman-4-ones
- 2-trichloromethylchromones
