Use of medium strength acid as an isomerization catalyst of the epoxide which includes the carbonyl functional group in rank vis-a-vis epoxide

摘要

(57) Abstract As for this invention, in the aforementioned epoxide which is melted in the medium whose polarity is low in regard to the method of isomerizing the epoxide which possesses the carbonyl functional group in epoxide rank, the pKa (measurement) 0 - 3 is in water medium and solubility in benzene it is low at least in the 50C - the 150C, (it features that it operates acid the symbol d in Handbook of Chemistry and Physics " or ). This invention is applicable in organic synthesis.
