Ferrocene tagged functional polymer: a robust solid-phase reagent for O-demethylation

Ferrocene tagged functional polymer was synthesized by exploiting the propensity of the Merrifield resin to undergo quaternization with N-ferrocenylmethyl benzimidazole followed by subsequent anion metathesis reaction. The synthesized polymer when employed as a solid-phase reagent for O-demethylation of aryl methyl ethers, showed TON in the range of 7373-8930 and TOF in the range of 279-494 h−1.
