meso-Stilbene dibromide is an organic compound with a formula of (C 6 H 5 CH(Br)) 2. [3] It is one of three isomeric stilbene dibromides, the others being the pair of enantiomers . All are white solids.
E)-Stilbene, commonly known as trans-stilbene, is an organic compound represented by the condensed structural formula C 6 H 5 CH=CHC 6 H 5. Classified as a diarylethene , it features a central ethylene moiety with one phenyl group substituent on each end of the carbon–carbon double bond .
Z)-Stilbene is a diarylethene, that is, a hydrocarbon consisting of a cis ethene double bond substituted with a phenyl group on both carbon atoms of the double bond. The name stilbene was derived from the Greek word stilbos , which means shining.
Alternatively stilbene is brominated, and the resulting dibromodiphenylethane is subjected to dehydrohalogenation. [3] Yet another method involves the coupling of iodobenzene and the copper salt of phenylacetylene in the Castro-Stephens coupling. The related Sonogashira coupling involves the coupling of iodobenzene and phenylacetylene.
Stilbene may refer to one of the two stereoisomers of 1,2-diphenylethene: -Stilbene (trans isomer) -Stilbene (cis isomer) See also. Stilbenoids, a class of ...
It is a white, water-soluble solid. Structurally, it is a derivative of trans-stilbene, containing amino and sulfonic acid functional groups on each of the two phenyl rings. The compound is a popular optical brightener for use in laundry detergents. It is produced by reduction of 4,4′-dinitro-2,2′-stilbenedisulfonic acid with iron powder. [1]

Pterostilbene is considered to be a corrosive substance, is dangerous upon exposure to the eyes, and is an environmental toxin, especially to aquatic life. [1] A preliminary study of healthy human subjects given pterostilbene for 6–8 weeks, showed pterostilbene to be safe for human use at dosages up to 250 mg per day, although this study did not assess metabolic effects on the lipid profile.
