METHOD OF PRODUCING DIISOBUTYL(2-ALKYL-3-(TRIMETHYLSILYL)CYCLOPROPYL)ALANES Russian patent published in 2011 - IPC C07F5/06

Abstract RU 2417227 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing diisobutyl(2-alkyl-3-(trimethylsilyl)-cyclopropyl)alanes of general formula (I): where R=n-C₄H₉, n-C₅H₁₁, n-C₆H₁₃, n-C₈H₁₇. The method involves reaction of 1-alkyl-2-(trimethylsilyl)acetylenes of general formula RC=CSiMe₃, where R is as described above, with triisobuylaluminium i-Bu₃Al in the presence of diiodinemethane CH₂I₂, taken in molar ratio 1-alkyl-2-(trimethylsilyl)acetylene : i-Bu₃Al : CH₂I₂=10:(25-35):(25-35). The reaction takes place in an argon atmosphere at temperature 20-22°C and normal pressure in dichloromethane for 3-5 hours.

EFFECT: invention enables production of diisobutyl(2-alkyl-3-(trimethylsilyl)-cyclopropyl)alanes of the formula given above.
