The author of the article were Borthwick, Scott; Foot, Jonathan; Ieva, Maria; McNab, Hamish; McNab, Lilian; Rozgowska, Emma J.; Wright, Andrew. The article conveys some information:
Independent generation of iminyl and pyrrol-1-yl radicals by flash vacuum pyrolysis of oxime ether I (X = N; R1 = MeO; R2 = 4-MeC6H4) and imine I (X = N; R1 = 4-MeC6H4; R2 = Me2N), resp., provided two regioisomeric pyrrolo[1,2-a]quinoxalines II. This shows that radical species interconvert via spirodienyl moiety at high temperatures Corresponding generation of pyrrol-1-yl radical from I (X = CH; R1 = 4-MeC6H4; R2 = Me2N) gave single pyrrolo[1,2-α]quinoline regioisomer as the only cyclized product. In this case, DFT calculations suggested that direct cyclization of pyrrol-1-yl took place, rather than formation of spirodienyl species and exclusive migration of C-N bond. In the experimental materials used by the author, we found 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Product Details of 696-59-3)
2,5-Dimethoxytetrahydrofuran(cas: 696-59-3) is a member of ether. When aromatic ethers are exposed to halogen in the presence or absence of a catalyst, they undergo halogenation, such as bromination.Product Details of 696-59-3
