The reaction of nonconjugated monosubstituted alkenes with t-BuMgCl and Cl2ZrCp2 at room temperature produces the corresponding monoalkylzirconium derivatives in high yields, while conjugated alkenes undergo either a novel t-butylzirconation or hydrozirconation depending on the reaction conditions.

Treatment of Cl2ZrCp2 with 2 equiv of alkylmetals (RM) containing Li or Mg, e.g., n-BuLi, in THF produces organozirconium species that act as sources of "ZrCp2," the latter product being a convenient reagent for preparing zirconacycles. We recently reported a bicyclization reaction of enynes3 with
