Reaction of Cp 2 TiCl 2 /Mg with propargyl acetates form allenyl titanium intermediates, which undergo nucleophilic addition reactions to aldehydes or ketones to give homopropargyl alcohols in high yields. Subsequent nucleophilic addition to acetonitrile and nucleophilic substitution with allyl brom
