Article abstract of DOI:10.1007/BF01185347

Irradiation of (Z)-α,β-diarylacrylonitriles (1) ArCH=C(CN)Ar' (a: Ar = 2-thienyl, Ar' = Ph; b: Ar = p-MeC6H4, Ar' = Ph) in the solid state gives cyclobutane dimers (2) in doog yield.The mass spectra of the dimers, where no fragments derived from dimers wi
