CATALYST FOR SYNTHESIS OF 1-DIALKYLAMINE-2,3-DIPHENYLALUMA- -CYCLOPROPENES Russian patent published in 2001 - IPC

Abstract RU 2175889 C2

FIELD: organic chemistry, chemical technology, catalysts. SUBSTANCE: catalyst for synthesis of 1-dialkyl- -amine-2,3-diphenylalumacyclopropenes is synthesized by interaction of cobalt dichloride CoCl2, activating addition triphenylphosphine Ph3P and dialkylaminoaluminium dichloride R2N-AlCl2 where R means Et, n-Bu, n-Hex as a reducing agent taken in the following mole ratio of components: CoCl2 : Ph3P : R2N-AlCl2 = 1:(1.5-2.5):(2-6), respectively. In the presence of indicated catalyst 1-dialkylamine-2,3-diphenylalumacyclo- -propenes are synthesized with yields 62-79%. EFFECT: increased yield of product. 1 tbl
