Abstract
A new synthetic approach to ethyl isobutyrylacetate based on magnesium ethoxide and magnesium chloride/triethylamine catalysis system has been studied.Optimum ratio of the reactants was as follows:n(isobutyryl chloride)∶n(potassium ethyl malonate)∶n(magnesium chloride)∶n(triethylamine)=1∶1.4∶1.68∶3.5;the reaction was conducted at 0~5 ℃ for 12 h.The highest yield gained in our experiments was 61%.
