CATALYST FOR SYNTHESIS OF 1-ALKYL-2,3-DIPHENYLALUMACYCLO-PROPENES Russian patent published in 2001 - IPC

Abstract RU 2175890 C2

FIELD: organic chemistry, chemical technology, catalysts. SUBSTANCE: catalyst for synthesis of 1-alkyl-2,3-di-phenylalumacyclopropenes is synthesized by interaction of cobalt dichloride CoCl2, activating addition triphenylphosphine Ph3P and alkylaluminium dichloride RAl-Cl2 where R means Et, n-Pr taken in the following mole ratio of components: CoCl2:Ph3P:RAl-Cl2 = 1: (1.5-2.5): (2-6), respectively. In the presence of indicated catalyst 1-alkyl-2,3-diphenylalumacyclo- -propenes are synthesized with yields 58-72%. EFFECT: increased yield of product. 1 tbl, 2 ex
