METHOD OF PREPARING 1-(ALKOXY)-2(2'-DIPHENYLETHYLENE)-3- PHENYLALUMACYCLOPROPANES Russian patent published in 2000 - IPC

Abstract RU 2145327 C1

FIELD: fine organic and organometallic synthesis. SUBSTANCE: described is method of preparing new 1-(alkoxy-2-(2'-phenylethylene-2- phenylalumocyclopropanes of formula I: wherein R is butyl of hexyl. Method comprises reacting 1,4-di- phenylbuta-1,3-diene with alkoxydichloroalanames of formula RO-AlCl2 and metallic magnesium at molar ratio of 10: (10-14):(10-14), respectively, in the presence of titanocene dichloride Cp2TiCl2 catalyst. Reaction is carried out in argon under normal conditions in tetrahydrofuran for 8-12 hours. Total yield of products is 72-89. EFFECT: high regioselectivity of the new compounds. 11 ex, 1 tbl
