FIELD: chemistry.
SUBSTANCE: invention refers to method of diethyl-[(2-ethyl-1,2-dialkylcyclopropyl) ethyl]-alans production and can be applied as catalyst system component in oligomerisation and polymerisation of olefine, diene and acetylene hydrocarbons, as well as in fine organic and organometallic synthesis. Production method of diethyl-[(2-ethyl-1,2-dialkylcyclopropyl)ethyl]-alans of general formula (I): 
is characterised by that 1,2-dialkylacetylene reacts with Et3Al with added CH2I2 taken in mole ratio 1,2- dialkylacetylene:Et3Al:CH2I2=10:(75-85):(35-45) in argon atmosphere in hexane at temperature 20-22°C and normal pressure during 10-14 h.
EFFECT: development of production method of new aluminium organic compounds.
