摘要

Takahashi et al. reported on the generation of cyclobutadienes from the reaction of zirconacyclopentadienes with CpCo(PPh 3 ) 2 . 4 Recently, we and another group reported the intramolecular coupling reaction of zirconacyclopentadienes in the presence of CuCl and benzoquinone produced cyclobutadiene derivatives, which easily transformed into cyclooctatetraene (COT) derivatives. 3 Accordingly, we envisioned that the coupling reaction of zirconaindenes 3 under ...
