Resonance Raman and density functional theory investigation of the photodissociation dynamics of the A-band absorption of (E)-β-nitrostyrene in cyclohexane solution

Visible light-mediated intermolecular [2 + 2] photocycloaddition of 1-aryl-2-nitroethenes and olefins

1-Aryl-4-nitrocyclobutanes were selectively prepared by intermolecular [2 + 2] photocycloaddition reactions from 1-aryl-2-nitroethenes upon irradiation with visible light (λ = 419 nm or λ = 424 nm).
