Collection: Imine Ligands

Imine Ligands — a collection of Schiff base compounds formed by the condensation of aldehyde or ketone groups with primary amines, producing imine groups (C=N) that act as nitrogen electron donors in the formation of metal complexes. Many members carry adjacent phenolic hydroxyl groups, enabling them to coordinate in both bidentate and tetradentate fashion.

Ligands such as N,N'-Bis(2-aminobenzal)ethylenediamine and N,N'-(Ethane-1,2-diylidene)bis(2,4,6-trimethylaniline) are commonly synthesized into salen complexes for asymmetric catalysis, for example epoxidation reactions, while salicylidene derivatives such as N-Salicylideneaniline are used in transition metal coordination studies. Researchers in inorganic chemistry and catalysis use them as a basic framework before complexing them with metals such as manganese, cobalt, or copper.

Example products in this collection: TCI A0261 4408-47-3 N,N'-Bis(2-aminobenzal)ethylenediamine, TCI B5606 74663-77-7 2,3-Bis(2,6-diisopropylphenylimino)butane, TCI S0328 1761-56-4 2-Salicylideneaminophenol, TCI E1383 56222-36-7 N,N'-(Ethane-1,2-diylidene)bis(2,4,6-trimethylaniline), TCI S0267 779-84-0 N-Salicylideneaniline, TCI F0893 3382-62-5 4-Fluoro-N-salicylideneaniline, TCI H1478 614-65-3 2-Hydroxybenzaldehyde Phenylhydrazone.

Please pay attention to purity and stability against reverse hydrolysis into the constituent aldehydes and amines, and ensure that substitutions on the aromatic rings, such as fluoro or methyl groups, match the electronic and steric requirements of the planned ligand. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on the page of each item.
