CATALYST FOR SYNTHESIS OF 1-ETHYL-2-(TRIALKYLXYLYL)-ALUMACYC- LOPROPANES Russian patent published in 2001 - IPC

Abstract RU 2175891 C2

FIELD: organometallic compounds, catalysts. SUBSTANCE: invention relates to catalyst used for synthesis of 1-ethyl-2-(trialkylxylyl)-alumocyclopropanes. The proposed catalyst is synthesized by interaction of cobalt dichloride CoCl2, activating addition of triphenylphosphine Ph3P and ethyl-aluminium dichloride EtAl-Cl2 as a reducing agent taken in the mole ratio = 1:(0.5-1.5):(2-6), respectively. EFFECT: availability and selectivity of catalyst. 1 tbl, 2 ex
