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.

The generation of allenic zirconium intermediates by treating propargylic ether derivatives with 'Cp2Zr' and their reactions with aldehydes in the presence of borontrifluoride etherate yield anti-β-acetylenic alcohols along with α-allenic alcohols.
