User:Salqu Ligand/Salqu Ligand

What is salqu?
a new chelating ligand used in coordination chemistry, homogeneous catalysis, solid phase extraction, sensor and pharmaceutical drugs. The name salqu is the abbreviation for salicylic aldehyde and 2-quinoxalinol. As an anionic tetradendate ligand, like salen, salqu also resembles tetradentate ligands including those that are macrocyclic, such as porphyrinate, corrin, bis(dimethylglyoximate), and some Schiff bases. Salqu was first prepared by Dr. Xianghong Wu and Dr. Anne Gorden who are from Auburn University. Therefore, catalysts based onto salqu ligands named after them, that is, Wu-Gorden catalysts. The major applications of salqu ligands and their metal complexes are 1, Solid phase extractors. 2, Catalysts for oxidation of aryl methylene group.

Preparation
It is often generated in methanol solvent followed by the addition of diamine-2-quinoxalinols and salicylaldehyde.
