METHOD OF PREPARING 1,2-BIS/(DIALKYLAMINE)ALUMA/CIS-1,2- DIPHENYL (ALKYL)ETHYLENES Russian patent published in 2000 - IPC

Abstract RU 2155768 C2

FIELD: metal and fine organic synthesis. SUBSTANCE: method comprises reacting bis(dialkylamine) aluminium chlorides wherein R′ is Et, n-C6H13 with disubstituted acetylene of formula: R-≡-R wherein R is Ph, n-C3H7, n-C4H9 and metallic magnesium at molar ratio of (25-35): 10:(10-14) in the presence of titanocene dichloride ((Cp2TiCl2)) in amount of 2-5 mole % with respect to disubstituted acetylene in argon atmosphere under normal conditions in hydrofuran during stirring operation for 8- 12 hours. The resulting new compounds are used as catalyst complex components in processes of polymerization and oligomerization of olefin and diene hydrocarbons and also in metallic and fine organic synthesis. EFFECT: more efficient preparation method. 1 ex, 1 tbl
