Abstrakt: A regio- and stereocontrolled method for the allylmetallation of 1-alkynes is described. The allylzirconium species, generated by hydrozirconation of allenes, undergo regioselective addition to 1-alkynes in the presence of organoaluminum reagents among which methylaluminoxane (MAO) is particularly effective. © 1997 Elsevier Science Ltd.
