METHOD FOR PREPARING 10-CHLORO-1,7,8,9-TETRAALKYL-4-METHYL-4-AZA-10-ALUMINATRICYCLO[5.2.1.02,6]DEC-8-ENE-3,5-DIONES

摘要

FIELD: chemistry of organoaluminum compounds, chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of compounds of the general formula (1): wherein R means ethyl (Et), n-propyl (n-Pr), n-butyl (n-Bu). Method involves interaction of disubstituted acetylenes with aluminum trichloride in the presence of metallic Mg (powder) and catalyst (Cp2ZnCl2) in argon atmosphere under atmosphere pressure and at room temperature for 8 h followed by addition of N-methylmaleinimide and stirring the reaction mass for 6-8 h at room temperature. The yield of the end substance is 76-85%. Synthesized compounds can be used in fine organic and metalloorganic synthesis and as co=catalysts in processes of oligomerization and polymerization of olefins and couples dienes. ^ EFFECT: improved method of synthesis. ^ 2 cl, 1 tbl, 1 ex
