Jb. Sheridan et al., ISOLATION AND CHARACTERIZATION OF A WELL-DEFINED PRECATALYST FOR THE RING-OPENING POLYMERIZATION OF SILICON-BRIDGED [1]FERROCENOPHANES, Journal of the Chemical Society. Dalton transactions, (5), 1997, pp. 711-713
Reaction of the silicon-bridged [1]ferrocenophane [Fe(eta- C5H4)(2)SiM
e(2)] with [Pt(cod)(2)] (cod = cycloocta-1,5-diene) yields a [2]platin
asilaferrocenophane [Fe(eta-C5H4)(2)Pt(cod)SiMe(2)] which functions as
a precatalyst for the ring-opening polymerisation of the silicon-brid
ged [Fe(eta-C5H4)(2)SiMe(2)] to yield the poly(ferrocenylsilane) [{Fe(
eta-C5H4)(2)SiMe(2)}(n)]; a key step in the mechanism is believed to i
nvolve dissociation of the cod ligand.
