A chelating tetrapeptide rhodium complex comprised of a histidylidene residue: biochemical tailoring of an NHC-Rh hydrosilylation catalyst

Coupling of a histidinium salt with a MetAlaAla amino acid sequence followed by metallation with [RhCl(cod)](2) yields a rhodium(I) NHC complex with a pending peptide residue. Methionine chelation, induced by chloride abstraction from the metal coordination sphere, affords an efficient hydrosilylati...

Zusammenfassung:Coupling of a histidinium salt with a MetAlaAla amino acid sequence followed by metallation with [RhCl(cod)](2) yields a rhodium(I) NHC complex with a pending peptide residue. Methionine chelation, induced by chloride abstraction from the metal coordination sphere, affords an efficient hydrosilylation catalyst precursor comprised of a peptidic macrocyclic chelate backbone.
