摘要

FIELD: organic synthesis. ^ SUBSTANCE: invention relates to new complexes of general formula I , wherein R is Et, i-Bu. Claimed method includes reaction of biscyclopentadienyl zirconium dihydride (Cp2ZrH2) with dialkylaluminum chlorides of general formula R2AlCl, wherein R is Et, i-Bu in Cp2ZrH2:R2AlCl molar ratio of 0.6:0.6 in argon atmosphere, at room temperature (approximately 20°C and atmospheric pressure in 0.5 ml of benzene-d6 for 5 min. Yield of target products is 80 %. ^ EFFECT: synthesis of complexes useful in hydrometalating of alpha-olefins. ^ 1 cl, 1 ex
