Reactions and characterization of allylic and related zirconium reaegnts (allenic and γ-alkoxyallylic zirconiums) generated by treatment of allylic and/or propargylic ethers with a zirconocene-butene complex ("Cp2Zr") are described.

The propargyltitanium reagents derived from 1-alkylpropyne condensed with aldehydes to give α-allenyl alcohol regioselectively, while the allenyltitanium reagents generated from 1-alkyl-1-butyne derivatives gave threo-β-acetylenic alcohols with high regio- and stereoselectivities.The course of the reaction was determined by the substitution pattern of starting alkynes.The similar reactions of metallated 1,3-bis(trialkylsilyl)propyne or (trialkylsilyl)acetonitrile with aldehydes were also investigated.
