Substrates containing aromatic rings have been attached to ‘polymer supported triphenylphosphine’ using a chromium carbonyl linker, chemically manipulated, and released from the polymer to demonstrate the potential use of π-bound ligands in linker chemistry. Immobilisation of the phenylalanine derivative Fmoc-Phe-OtBu via its aromatic ring has been achieved and the resulting resin successfully subjected to standard amino acid deprotection and coupling procedures.
