User:Salqu Ligand

What is salqu?
Salqu is a new chelating ligand used in coordination chemistry, homogeneous catalysis, solid phase extraction, sensor and pharmaceutical drug. The name salqu is the abbreviation for salicylic aldehyde and 2-quinioxalinols. As an anionic tetradendate ligand, like salen, salqu 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.

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