“…[13] Reaction with [Ru 3 (CO) 12 ] affords the structural analogues 13 and 14. [14] Chiral heterotrinuclear hydrido clusters of type [(m-RC)CoM 1 M 2 Cp(CO) 8 H] (R Me, Ph; M 1 Ru, Os; M 2 Mo, W) react with the prochiral alanine precursor methyl acetamidoacrylate with insertion into the M ± H function and substitution of a CO ligand (15 ± 18).…”

A new, interdisciplinary research area has emerged known as bioorganometallic chemistry. It focuses on the introduction of organometallic fragments into biomolecules (see, for example, structure on the right). "Classical" α-amino acid and peptide ligands have proven particularly versatile, and provide access to compounds that display interesting stereochemistry. α-Amino acids and peptides can be synthesized, labeled, stabilized, or activated by organometallic fragments.

“…Only a few organometallic complexes containing amino acidato bridges have been reported. Some representative examples are [Os 3 (CO) 9 (μ-XCH 2 (CO 2 Et)NH 2 ] (X = O, S) and [Ru 3 (CO) 9 (μ-H)(μ-SCH 2 (CO 2 Et)NH 2 ] . In both cases the amino ester uses the O or S atom of the pendant chain to bridge two atoms of the same metal.…”

The addition of NaOMe to [MnMo(CO) 6 (µ-S 2 CPCy 3 )(µ-Br)] (1) produces [MnMo(CO) 6 (µ-S 2 CPCy 3 )(µ-OMe)] (2), containing a methoxide bridge between Mn and Mo. Compound 2 reacts with R-amino acids to yield, upon elimination of MeOH, the complexes [MnMo(CO) 5 -(µ-S 2 CPCy 3 ){µ-OC(O)CR 1 R 2 NR 3 2 }] (3a-f), in which the oxygen atom of the carboxylato group acts as a bridge between Mn and Mo, while the amino function coordinates the molybdenum atom, displacing one carbonyl ligand. In a similar reaction, the addition of ethanolamine to 2 affords the µ 2 (O)-η 2 (O,N)-aminoethanolato complex [MnMo(CO) 5 (µ-S 2 CPCy 3 )(µ-OCH 2 CH 2 -NH 2 )] (4). Reaction of 2 with cysteine methyl ester hydrochloride and NaOMe affords [MnMo-(CO) 5 (µ-S 2 CPCy 3 ){µ-SCH 2 C(COOMe)NH 2 }] (5), with the sulfur atom in the bridging position. The new complexes have been characterized by analytical and spectroscopic methods, and their structures have been determined by X-ray crystallography for 2, 3e (2,2-dimethylaminobutyrato), and 4.
