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.
