METHOD OF COMBINED PREPARATION OF 1-(DIALKYLAMINO)-2- PHENYLALUMA CYCLOPENTANE AND 1-(DIALKYLAMINO)-2,4- DIPHENYLALUMACYCLOPENTANE Russian patent published in 2000 - IPC

Abstract RU 2156771 C2

FIELD: chemical industry. SUBSTANCE: described is method of combined preparation of new 1-(dialkylamino)-2-phenylalumacyclopropane of formula I: and 1-(dialkylamino)-2,4-diphenylalumacyclopentane of formula II: wherein R is Et, n-Bu and which comprises reacting styrene n-C6H12 with dialkylaminodichloro alanes of general formula: R2N-AlCl2:Mg and metallic magnesium at ratio of 10(10-14): (10-14) in the presence of zirconium tetrachloride catalyst in amount of 3-5 mole % with respect to styrene, and reaction is carried out in argon atmosphere under normal conditions in tetrahydrofuran. Method is applicable in fine organic and organometallic synthesis and makes it possible to prepare simultaneously new 1-(dialkylamino)-2- phenylalumacyclopropanes and 1-(dialkylamino)-2,4- diphenylalumacyclopentanes with high regioselectivity. EFFECT: more efficient preparation method. 11 ex, 1 tbl
