FIELD: chemical technology. SUBSTANCE: invention describes a method of synthesis of 1-ethyl-2-aryl-3-methylenealumacyclopropanes of the general formula (1) where Ar is Ph, p-CH3Ph characterized in that arylallenes of the general formula Ar- =•= where Ar is determined above is subjected for interaction with ethylaluminum dichloride (EtAlCl2) and metallic magnesium taken in mole ratio Ar-=•= : (EtAlCl2) : Mg = 10:(10-14): :(10-14), respectively, in the presence of a catalyst (Cp2TiCl2) taken in the amount 2-6 mole % with respect to arylallene in tetrahydrofuran medium. Reaction is performed in argon atmosphere at the room temperature (~20 C) under normal pressure for 6-10 h. The proposed method of synthesis can be used in industrial organic synthesis, in part, in polymerization processes where synthesized compounds take part of cocatalysts. EFFECT: improved method of synthesis. 1 tbl, 10 ex
