FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to the improved method for preparing acylated 1,3-dicarbonylic compounds used as agrochemicals or intermediate products in manufacturing agrochemicals. Also, invention describes a method for preparing tautomeric forms of acylated 1,3-dicarbonylic compounds. Method involves the arrangement reaction of the corresponding enol ester and this rearrangement reaction is carried out in the presence of alkaline metal azide. Method provides eliminating the requirement in expensive isolating process of catalyst/reagent in systems for waste treatment.
EFFECT: improved preparing method.
