Functional ligands and complexes for new structures, homogeneous catalysts and nanomaterials

Structures, Redox and Spectroscopic Properties of PdII and PtII Complexes Containing an Azo Functionality

“…[12] In recent years, complexes of cis-dichloropalladium(II) have found use as catalysts and pre-catalysts in a variety of organic transformations. [13] Azo ligands, on the other hand, continue to play an important role in coordination chemistry, [(az)Pt(µ-Cl) 2 Pt(az)] (4) shows reduction processes which are reversible for 1 and 2 but irreversible for 3 and 4. The first reduction of 1 and 2 leads to radical complexes, and EPR spectroscopy shows the spin to be predominantly located on the azo part of the complexes.…”

The synthesis of functional mesoporous materials

“…More sophisticated ligand design allows the synthetic chemist to tailor these materials to chelate specific classes of metals, making ligand design a key component of the design and construction of these materials [124]. For example, the acetamide phosphonate and propionamide phosphonate ligands (in both their ester and acids forms) have been shown to be selective for the lanthanides [125] and actinides [126], even in the presence of large excesses of competing transition metal cations.…”

STRUCTURAL AND PHOTOPHYSICAL PROPERTIES OF A MONONUCLEAR Re(I) COMPLEX:[P,N-{(C6H5)2(C5H5N)P}Re(CO)3Br]

“…hardness, coordinating ability or trans-effect, add possibilities during a for example catalytic cycle, which could be used to tune the reaction to a specific target. [1][2][3][4][5][6] Particularly, many attention have been devoted to the molecule diphenylpyridylphosphine, (C 6 H 5 ) 2 (C 5 H 5 N)P, synthesized 35 7 years ago (structurally determined in 1989 8 ). The molecule is a rigid bidentate ligand with a short bite of 2.5 Å (see scheme 1).…”
