Zwitterionic Ni(II) complexes bearing pyrazolyl-ether-imidazolium ligands: synthesis, structural characterization and use in ethylene oligomerization

The cobalt complexes show a significant growth inhibition of yeasts tested and also to fungi of the genus Scedosporium which is of interest because these fungi are usually

Potentially bidentate hybrid ligands (containing a NHC donor associated with an ether or an amine) and tridentate NCN pincer-type ligands (containing a central NHC donor

Synthesis and characterization of oxygen-functionalized-NHC silver(I) complexes and transmetallation to nickel(II) Sophie Hameury,' Pierre de Frémont,' Pierre-Alain R. In contras!,

Nickel complexes associated with diimine ligands and acti- vated with MAO are more active for the oligomerization of ethylene in biphasic chloroaluminate ionic liquid systems than

Chelated on iron or cobalt, ligands 22 led to inactive catalysts for the ethylene transformation, while on titanium or chromium, high activities were obtained for

approximately 7 days the formation of crystalline material 1 was occurred; a few selected single crystals were used for the X-ray diffraction analysis (see ESI for

In particular, studies involving pyrrolyl-based chromium catalyst systems have shown that different catalytic behavior can be achieved depending on the nature of the ancillary

Our group have been studied the hydrogen transfer using different ruthenium complexes containing polypyridine ligands which showed that the complex containing polypiridine
