Abstract

A general method for immobilization of synthetic analogues of the [FeFe]-hydrogenase in designed peptides via on resin modification of an amino acid side chain with a dithiol functional group is described. Utilizing a unique amine side chain as anchor, the dithiol unit is coupled to the peptide via formation of an amide. This dithiol unit precisely positions the two required sulfur atoms for the formation of a [(μ-SRS){Fe-(CO)3} 2] cluster on reaction with [Fe3(CO)12]. UV/Vis and FTIR spectroscopy demonstrate formation of the desired complex.
