Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya called Competing electrophilic aromatization of methylene-1,3- and -1,4-cyclohexadienes, Author is Rozenberg, V. I.; Nikanorov, V. A.; Gorbacheva, R. I.; Reutov, O. A., which mentions a compound: 57825-30-6, SMILESS is CCC1=CC=C(CBr)C=C1, Molecular C9H11Br, SDS of cas: 57825-30-6.
Reaction of 5:1 5-ethyl-6-methylene-1,3- (I) and 3-ethyl-6-methylene-1,4-cyclohexadiene (II) with HgCl2 followed by reduction with LiAlH4 gave 5:1 2- (III) and 4-EtC6H4Me (IV) in 90% overall yield. Adding a 10-fold excess of HCl gave 50:1 III-IV. Reaction of 5:1 I-II with AuBr3 or (Ph3P)AuBr3 gave 3.8:1 III-IV in 17 and 85% combined yield, resp.
Although many compounds look similar to this compound(57825-30-6)SDS of cas: 57825-30-6, numerous studies have shown that this compound(SMILES:CCC1=CC=C(CBr)C=C1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
