Allyl alcohols and ethers were readily hydroaluminated by LiAlH 4 in the presence of zirconium compounds to give organoaluminum compounds in which the aluminum atom is placed at the terminal position of the substrate. ZrCl 4 was the most effective catalyst for hydroalumination of allyl alcohols, whilst Cp 2 ZrCl 2 was more effective than ZrCl 4 for allyl ethers.
