We report the first chemoselective, high yield synthesis of monosubstituted
rhodocenium through a “η5 → η4 → η5
” strategy detailing sequential nucleophilic addition
and endohydride abstraction. Monosubstituted rhodocenium derivatives are then used as
versatile synthons for the preparation of the first-ever vinyl monomers that allow controlled
polymerizations including ROMP and RAFT, leading to rhodocenium-containing
metallopolymers. Exploratory ion-exchange and self-assembly of this new class of
polyelectrolytes cultivates the potential of side-chain rhodocenium-containing polymers.
