METHOD FOR PREPARING 11-CHLORO-1,8,9,10-TETRAALKYL-11-ALUMINATRICYCLO6.2.1.0^2,7UNDEC-9-ENE-3,6-DIONES

摘要

FIELD: chemistry of metalloorganic compounds, chemical technology.;SUBSTANCE: invention relates to a method for synthesis of novel organoaluminum compounds of the general formula (I): 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 Cp₂ZrCl₂ as a catalyst in argon atmosphere, at room temperature for 8 h followed by addition of p-benzoquinone and stirring the reaction mass for 2-4 h at room temperature. The yield of the end substance is 55-60%. Synthesized compounds can be used in fine organic and metalloorganic synthesis and as co-catalysts in processes of oligomerization and polymerization of olefins and coupled dienes.;EFFECT: improved method of synthesis.;2 cl, 1 tbl, 4 ex
