Stepwise activation of “non-innocent” Cp* substituents – a Cp* based cascade reaction

Zusammenfassung

Reactions of Cp* substituted pentelidene complexes with the primary phosphine Cp*PH2 yield novel polycyclic phosphorus/arsenic and carbon containing cage compounds via cascade-like reactions. These reactions include a sequence of nucleophilic addition reactions, intramolecular hydrophosphination (partially hydroarsination) reactions, retro-Diels–Alder reactions with Cp*H elimination and subsequent [2+4]-cycloadditions.
