摘要：

Zirconium-alkyne complexes or zirconacyclopentenes, which were easily prepared in situ from alkynes, reacted with acrolein diethylacetal to afford vinyl ether derivatives. The C-C bond formation proceeded exclusively at beta-position of the alpha,beta-unsaturated acetal. Zirconium catalyzed C-C bond formation reactions of alpha,beta-unsaturated acetals with EtMgBr also proceeded at beta-position exclusively.
