X-ray structural analysis and catalytic properties of new thiazoline-carboxylate ruthenium complexes

Role of X-Ray Crystallography in Structural Studies of Pyridyl-Ruthenium Complexes

It is extremely important for chemists to establish the structure of new compounds. A more accurate understanding of the structure leads to the construction of appropriate reaction systems. For example, although the well-known platinum complex, [PtCl2(NH3)2], has two geometrical isomers (cis and trans in Fig. 1), only the cis-isomer (so-called cisplatin) exhibits prominent antitumor activity (R...

Structural modulation of silver complexes and their distinctive catalytic properties.

A family of silver(I) complexes, [Ag2(L)2(OOCCF3)2] (1), [Ag(L)0.5(OOCCF3)] (2), [Ag(L)2](OOCCF3)(H2O)2 (3), was obtained by reactions of 4,4'-di(2-oxazolinyl)biphenyl (L) and AgOOCCF3 in different reaction media. Compound 1 has a 1D chain structure with alternative connections between the Ag(I) and L ligand. When the crystal nucleation inductor, pyrazine, was added into the reaction system, co...

Synthesis and catalytic activity of histidine-based NHC ruthenium complexes.

Main-chain C,N-protected histidine has been successfully alkylated at both side-chain nitrogens. The corresponding histidinium salt was metallated with ruthenium(II) by a transmetalation procedure, thus providing histidine-derived NHC ruthenium complexes. These bio-inspired complexes show appreciable activity in the catalytic transfer hydrogenation of ketones.
