Treatment of (E)-2-methyl-1-alkenylalanes (1), readily obtainable via Zr-catalyzed reaction of Me3Al with 1-alkynes, with E-methoxydialkylboranes produces the corresponding alkenylboranes, while sequential treatment of 1 with n-BuLi and X2ZrCp2 (X=Cl or I) provides the desired monoalkenylzirconium derivatives, the product yields for both reactions being 85-100percent.
