METHOD OF PREPARING 1-ALKOXY (OR DIALKYLAMINO)-2,3- DIPHENYL(ALKYL)ALUMACYCLOPROPENES Russian patent published in 2000 - IPC

Abstract RU 2151772 C1

FIELD: chemical industry. SUBSTANCE: described is method of preparing 1- alkoxy (or dialkylamino)-2,3- diphenyl(alkyl)alumacyclopropene of general formula I: wherein R is OEt, OBu, NEt2, , R1 is Ph, C3H7, C4H9. Said method comprises reacting alkoxy (or dialkylamino)aluminium chloride RAlCl2 with disubstituted acetylene R1-≡-R1 and magnesium at (10-12): (1-12) ratio respectively in the presence of titanocene dichloride ((Cp2TiO2)), and process is carried out in argon atmosphere under normal conditions in tetrahydrofuran for 10-14 h. Said method make it possible to prepare new 1-alkoxy (or dialkylamino)-2,3-diphenyl(alkyl) alumacyclopentanes having high regioselectivity. EFFECT: more efficient preparation method. 14 ex, 1 tbl
