Abstract

Способ получения эфиров 4,5-дибром-2-гексеновой кислоты общей формулыCH(CHBr)CH=CHCOOR,где R означает метил, этил или н-пропил, включающий стадии взаимодействия сорбиновой кислоты, соответствующего спирта и молекулярного брома, отличающийся тем, что, с целью упрощения процесса и повышения стереоспецифичности реакции, сорбиновую кислоту подвергают взаимодействию с молекулярным бромом в среде соответствующего спирта при мольном соотношении сорбиновая кислота:молекулярный бром:спирт, равном 1:(1-1,5):(9÷11).The method of producing 4,5-dibromo-2-hexenoic esters of the general formula CH (CHBr) CH = CHCOOR, where R is methyl, ethyl or n-propyl, which includes the reaction of sorbic acid, the corresponding alcohol and molecular bromine, characterized in that in order to simplify the process and increase the stereospecificity of the reaction, sorbic acid is reacted with molecular bromine in the environment of the corresponding alcohol at a molar ratio of sorbic acid: molecular bromine: alcohol, equal to 1: (1-1.5) :( 9 ÷ 11).
