Mohr, Lisa-Marie published the artcileIntermolecular [2+2] Photocycloaddition of β-Nitrostyrenes to Olefins upon Irradiation with Visible Light, Recommanded Product: (E)-4-(2-Nitrovinyl)benzonitrile, the publication is Synlett (2017), 28(20), 2946-2950, database is CAplus.
The title compounds were found to undergo a [2+2] photocycloaddition with olefins at λ = 419 nm in CH 2Cl 2as the solvent. The resulting cyclobutanes were isolated in yields of 32-87% (11 examples) and showed a defined relative configuration at C1/C4 in the major diastereoisomer (nitro and aryl trans). The anal. of side products and triplet sensitization experiments support a mechanistic scenario in which a 1,4-diradical is formed as a key intermediate.
Synlett published new progress about 5153-73-1. 5153-73-1 belongs to nitriles-buliding-blocks, auxiliary class Nitrile,Alkenyl,Nitro Compound,Benzene, name is (E)-4-(2-Nitrovinyl)benzonitrile, and the molecular formula is C9H6N2O2, Recommanded Product: (E)-4-(2-Nitrovinyl)benzonitrile.
