METHOD FOR PRODUCING diisobutyl (2-isobutyl-1-ALKILTSIKLOPROPIL) ethyl Alan

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method of producing diisobutyl-[(2-isobutyl-1-alkylcyclopropyl)-ethyl]alanes with general formula (1): (1), where R=H-C₄H₉, H-C5H₁₁, H-C₆H₁₃, characterised by that terminal alkylacetylene with general formula RC≡CH, where R= H-C₄H₉, H-C₅H₁₁, H-C₆H₁₃ is reacted with triisobutylaluminium i-Bu₃Al in the presence of diidomethane CH₂I₂, with molar ratio of terminal alkylacetylene: i-Bu₃Al: CH₂I₂=10:(55-65):(35-45) in an argon atmosphere at temperature 20-22°C and normal pressure in dichloromethane for 16-20 hours.;EFFECT: use of present method enables production of said compound with high regioselectivity.;1 cl, 2 ex, 1 tbl
