METHOD FOR PRODUCTION OF BIMETAL COMPLEXES OF μ, μ-DIHYDRO-BIS-[HYDRO-μ, CHLORODIALKYLALUMINUM (BISCYCLOPENTADIENYL ZIRCONIUM(IV))] Russian patent published in 2006 - IPC C07F17/00 C07F5/06

Abstract RU 2283845 C1

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-d₆for 5 min. Yield of target products is 80 %.

EFFECT: synthesis of complexes useful in hydrometalating of α-olefins.
