Manners and co-workers recently described the preparation of polyferrocenylsilane.137 The polymerization occurred through living anionic ring-opening of ethylmethylsila[l]ferroceno-phane with n-BuLi. The polymers obtained possessed molecular weights (A/n) between 4000 and 41,400, with PDI = 1.01-1.02. 

The first PFS-fr/ock-polymethacrylate copolymer was reported in 2002 28 The procedure involved a two-step anionic polymerization (Scheme 3.7). Hydroxy terminated polyferrocenylsi-lane (PFS-OH) was initially synthesized using r-butyldimethylsilyloxy-1-propyllithium as an initiator bearing a protected alcohol functionality. Once isolated, PFS-OH was deprotonated using potassium hydride to afford the alkoxy chain end that initiates dimethylaminoethyl methacrylate (DMAEMA) for anionic polymerization. The PFS- -PDMAEMA block copolymer was obtained in a high yield (Mn = 11,000 PDI =1.3) and with a low polyferrocenylsilane content (PFS PDMAEM A = 1 5).
