FIELD: organometallic synthesis. SUBSTANCE: preparation of volatile rare-earth element acetylacetonates of general formula I: 
(I), in which Ln represents rare-earth element atom, is characterized by conducting electrolysis of acetylacetone-lithium solution in acetonitrile [weight ratio (1-10):1:500] with rare-earth metal anode (potential 0.5-1 V) and inert cathode, using asymmetric alternate current generated by inserting into electric circuit, in series with electrolyzer, unit semiconductor diode. Resulting solid product is washed with absolutely anhydrous ethanol and dried. EFFECT: enabled single-stage process. 3 cl, 1 dwg, 1 tbl, 2 ex
