Abstract
Способ получения фторалкилсодержащих α, β-эпоксикетонов общей формулыгде R- CF, CF, CF, H(CF);R - Ph, t - Bu,на основе фторалкилсодержащих β-гидроксикетонов общей формулыгде Rи R имеют указанные выше значения, отличающийся тем, что, с целью упрощения процесса и увеличения выхода целевого продукта, вышеуказанный кетон подвергают взаимодействию с эквимолярным количеством брома в присутствии карбоната кальция в среде алифатического углеводорода или галоидуглеводорода с последующим кипячением реакционной массы с водным раствором карбоната натрия при молярном соотношении кетон - карбонат натрия 1:5-6.The method of obtaining fluoroalkyl-containing α, β-epoxyketones of the general formula where R is CF, CF, CF, H (CF); R is Ph, t is Bu, based on the fluoroalkyl containing β-hydroxyketones of the general formula where R and R have the above values, characterized in that In order to simplify the process and increase the yield of the target product, the above ketone is reacted with an equimolar amount of bromine in the presence of calcium carbonate in an aliphatic hydrocarbon or halohydrocarbon, followed by boiling the reaction mixture with an aqueous solution of sodium carbonate at olyarnom ketone ratio - Sodium carbonate is 1: 5-6.
