FIELD: organic chemistry. SUBSTANCE: invention relates to a method of synthesis of new compounds, - 6,8,10-trinitro-1,4-dioxaspiro- -[4,5]deca-6,9-dienates of cations of p-, d- and f-elements of the formula (I) 
(anionic σ-Meisengeimer complexes) where Kt is 
; n - index corresponding to the valency of cation Kt that can be used for metal-chelate catalysis. Method involves synthesis of 6,8,10-trinitro-1,4-dioxaspiro[4,5]deca-6,9-dienate sodium from 2,4,6-trinitroanisole and ethylene glycolate sodium. The end compound is subjected for reaction of ionic exchange with inorganic salt or hydroxide of the corresponding metal in an aqueous-ammonium medium. Method exhibits the technological pattern since the available, stable and reactive ethylene glycolate sodium is used as the parent compound. EFFECT: improved method of synthesis.
