Abstract
The tricyclic zirconocene-phosphaalkyne dimer complex 1 reacts with diethyl mesoxalate (5) or tetracyanoethene (7) through Cp2Zr-displacement to furni sh the novel oxadiphosphatricyclohexane 6 or the diphosphatricyclohexane 8, respectively. In contrast, treatment of 1 with indanetrione (9) results in the formation of the dioxadiphosphatricyclooctene 10, which has been chara cterized by X-ray structure analysis.
