Abstract :
Zirconacyclopentadienes reacted with benzal halides in the presence of CuCl and dimethylpropyleneurea to give pentasubstituted cyclopentadienes in moderate to good yields. Treatment of zirconacyclopentadienes with 1,1-dibromo-1-alken-3-yne and 1,1-dibromo-1,3-alkadiene afforded fulvene derivatives in good yields.
