METHOD OF PREPARING 1-(DIALKYLAMINO)-2-PHENYL (ALKYL)ALUMACYCLOPROPANES Russian patent published in 2000 - IPC

Abstract RU 2156770 C2

FIELD: chemical industry. SUBSTANCE: described is method of preparing new 1- (dialkylamino)-2-phenyl(alkyl)alumacyclopropanes of formula I: 1 wherein R is n-C4H10,n-C6H13,R1-Ph,n-C6H13,n-C8H17 and are useful in fine organic and organometallic synthesis. Method comprises reacting alpha-olefin with dialkylamino dichloroalane R2N-AlCl2 and metallic magnesium at weight ratio of 10:(10- 14):(10-14), respectively, in the presence of tetraisopropaneoxy titanium, tetrabutoxy titanium or titanocene dichloride catalyst in amount of 2-6 mole % with respect to alpha-olefin in argon atmosphere under normal conditions in tetrahydrofuran. Reaction time is 6-10 hours. Total yield of the desired products is 62-84 %. Method makes it possible to prepare new 1- (dialkylamino)-2-phenyl(alkyl)alumacyclopropanes having high regioselectivity. EFFECT: more efficient preparation method. 12 ex, 1 tbl
