摘要：

Low-valent titanium alkoxide prepared from Ti(O-i-Pr)(4) and i-PrMgCl (1:2) incorporates acetylene to give an acetylene complex, titanacyclopropene, as evidenced by its reaction with deuterium oxide. Carbonyl compounds likewise reacted with the acetylene complex to give allyl alcohols. Introduction of two different electrophiles at each of both acetylenic termini was possible in a regio- and stereo-selective manner.
