Isolation and characterisation of a well defined precatalyst for the ring-opening polymerisation of silicon-bridged [1]ferrocenophanes

Abstract

Reaction of the silicon-bridged [1]ferrocenophane [Fe(η-C₅H₄)₂SiMe₂] with [Pt(cod)₂] (cod = cycloocta-1,5-diene) yields a [2]platinasilaferrocenophane [Fe(η-C₅H₄)₂Pt(cod)SiMe₂ ] which functions as a precatalyst for the ring-opening polymerisation of the silicon-bridged [Fe(η-C₅H₄)₂SiMe₂] to yield the poly(ferrocenylsilane) [{Fe(η-C₅H₄)₂SiMe₂ }_n]; a key step in the mechanism is believed to involve dissociation of the cod ligand.
