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

Abstract RU 2145328 C1

FIELD: fine organic and organometallic synthesis. SUBSTANCE: described is method of preparing new 1-(dialkylamine)-2- (2'-phenylethylene-3-phenylalumacyclopropanes of formula I: wherein R is ethyl, butyl or hexyl. Method comprises reacting 1,4-diphenyl-1,3-butadiene with dialkylamine dichloroalanams of formula: R2N-AlCl2 and metallic magnesium at molar ratio 10: (10-14): (10-14), respectively, in the presence of titanocene dichloride in argon atmosphere under normal conditions in tetrahydrofuran for 8-12 hours. Total yield of the desired products is 64-87%. EFFECT: more efficient preparation method. 11 ex, 1 tbl
