Yang, Fanglong,Zhao, Gang,Ding, Yu
, p. 2839 - 2841 (2007/10/03)
Reaction of Cp2TiCl2/Mg with propargyl acetates form allenyl titanium intermediates, which undergo nucleophilic addition reactions to aldehydes or ketones to give homopropargyl alcohols in high yields. Subsequent nucleophilic additio

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.
