A new route to poly(ferrocenylsilanes) under mild conditions via the ring-opening polymerization of silicon-bridged [1]ferrocenophanes is presented. Catalytic amounts of the transition metal complexes [Rh(cyclooctene)(2)(mu-Cl)](2), Pd(1,5-cycloocladiene)Cl-2, PdCl2 and PtCl2 in C6D6 at room temperature afforded high molecular weight poly(ferrocenylsilanes) (2). In some cases a symmetrical dimer (3) was obtained as a byproduct.
