The rearrangement of acetylenic epoxides mediated by low-valence organotitanium and organozirconium reagents is -reported to give conjugated enynes. Moderate to good yields and high selectivities are obtained when using the organozirconium(II) Negishi rea

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.
