Chiral Chloro-Bridged η6-Phenylglycine Ruthenium(II) Complexes Formed by Dehydrogenation of (R)-2,5-Dihydrophenylglycine

Synthesis and Characterization of Tetrahedral Ru3O Clusters with Intrinsic Framework Chirality: A Chiral Probe of the Intact Cluster Catalysis Concept

“…Since the diastereomers ( S , R )- 7 and ( R , R )- 7 turned out to be inseparable in our hands, we synthesized an analogous cluster containing an amido and an ester function on the chiral substituent at one of the arene ligands. The chiral dimer ( S , S )-[Ru{C 6 H 5 (CH(NHCOMe)CO 2 Et)}Cl 2 ] 2 described in the literature was used as the starting material for the reaction with the trihydrido dinuclear complex 4 in aqueous solution.

“…12 000 interferograms were averaged. The complexes [Ru(C 6 Me 6 )Cl 2 ] 2 , [Ru( p -Pr i MeC 6 H 4 )Cl 2 ] 2 , [Ru(C 6 H 6 )Cl 2 ] 2 , [Ru(COD)(C 10 H 8 )],26a ( S , S )-[Ru{C 6 H 5 (CH(NHCOMe)CO 2 Et)}Cl 2 ] 2 , and [H 3 Ru 2 (C 6 Me 6 ) 2 ] + were prepared according to literature procedures. Although the synthesis of the ligand 10 was already described in the literature, the method employed here was slightly different.…”

Crystal structure of N-acetyl-D-2-(1,4-cyclohexadienyl)glycine ethyl ester, C12H17NO3

“…of chloro-bridged phenylglycine ruthenium complexes [2]. The distances in the six-membered ring exhibit a typical 1,4-cyclohexadiene in the chair conformation (d(C2-C7) = 1.325 (2) A,…”

Chiral separation of substituted phenylalanine analogues using chiral palladium phosphine complexes with enantioselective liquid–liquid extraction

“…The absorption band at 3309 cm -1 can be assigned to the stretching vibrations of the primary amine group coordinated to the palladium metal center. 47 To confirm the coordination of the amine to the palladium, a comparison between the tryptophan palladium complex and the tryptophan sodium complex (H 2 N-CHR-CO 2 Na) was made by FTIR spectrscopy. The FTIR spectra of the complexes are depicted in Fig.…”
