Vanadium(V)-Promoted Sulfoxidation in the Presence of Schiff Base of Glucosamine

A series of Schiff-base ligands derived from 6-aminoglucose and various salicylaldehyde derivatives introducing different electronic and steric effects were synthesized and fully characterized. These ligands were used in vanadium-promoted sulfoxidation reactions and tested for their influence on the activity of the employed catalytic system. Generated catalysts perform superior to pre-prepared complexes.
