摘要

FIELD: components of catalyst systems in processes of oligomerization and polymerization of olefins and diene hydrocarbons, more particularly fine organic and organometal synthesis. SUBSTANCE: method comprises reacting terminal acetylenes of formula: wherein R is ¡-C5H11, ¡-C6H13, Ph with ethylalumium dichloride and metallic magnesium in the presence of zirconacene dichloride. Reaction is carried out in argon atmosphere under normal conditions for 8-12 hours. Yield of desired products is 62-81%. EFFECT: more efficient preparation method. 2 cl, 12 ex, 1 tbl
