Abstract
The novel polymerizable ferrocenes 8 (Scheme 2) and 11 (Scheme 3) have been
synthesized, and cationic polymerization experiments towards bridged poly(
1,1'-diisopropenyl)ferrocenes 1 as well as poly(1,1',3,3'-tetraisopropenyl)
)ferrocenes 2 are discussed. In both cases, only oligomeric products with
(M) over bar n ca. 1700/(M) over bar(w) of ca. 2900 (1) and (M) over bar(n)
ca. 1400/(M) over bar(w) of ca. 4000 (2) have been isolated. On the other
hand, synthetic attempts towards polyferrocenophanes 3 (Scheme 6) result in
oligomeric products as well.
