Iminostilbene Chemical Properties,Uses,Production

Chemical Properties

Yellow to orange-yellow fine powder

Uses

Iminostilbene is mainly used as a pharmaceutical intermediate for the production of carbamazepine, Oxcarbazepine, and rhodium catalyst ligand. It is a metabolite of of carbamazepine which is used primarily in the treatment of epilepsy and neuropathic pain.

Preparation

iminostilbene synthesis: 10,11-Dihydro-5-dibenz(b,f)azepine [Iminodibenzyl, 494-19-9] as raw material was acylated by triphosgene, after bromination by bromine and dehydrobromination, reacted with sodium hydroxide in isopropanol to give Iminostilbene.

Definition

ChEBI: Iminostilbene is a mancude organic heterotricyclic parent that consists of a seven-membered nitrogen hetrocycle fused with two benzene rings. It has a role as a marine xenobiotic metabolite. It is a mancude organic heterotricyclic parent and a dibenzoazepine.

Application

Iminostilbene has good antioxidant effects. N-acetyl iminostilbene was synthesized by incubating iminostilbene (2.0020 g, 10.360 mmol) with acetic anhydride.

General Description

5H-Dibenz[b,f]azepine, a tricyclic amine with a seven-membered ring, is commonly known as iminostilbene. It is used as an intermediate or a starting material in the synthesis of many anticonvulsant drugs.It is also used as a starting material to prepare pharmacologically important dibenzoazepine-pyridazine derivatives and synthesize olefinic multidentate ligand, which is used to prepare Rh(I) complexes.

Biochem/physiol Actions

2-(Bromomethyl)naphthalene is a fluorescent alkyl bromide. It causes the esterification of free carboxyl groups formed at the surface of polyethylene terephthalate by enzyme hydrolysis. It acts as organic electrophile in the P4S10/acyloin reaction.
