Краткое описание
1, 1-Dicyano-2-phenyl-1,8a-dihydroazulene (H-D) and a series of p-phenyl-substituted derivatives (R-D, R; NO 2 , CN, Br, Cl, CH 3 , OCH 3 , and NH 2 ) were investigated by time-resolved and steady-state photochemical methods. Th edihydroazulenes (DHAs) undergo an efficient photoreaction to the correspondingvinylheptafulvenes (VHFs), the quantum yield (Φ D→V ) at room temperature ranges from 0.1 to 0.6. The VHFs (λ v =440-470 nm) are nonemitting and photochemically nonreactive and undergo a thermal rearrangement. The activation energy for this back-reaction is 18-21 kcal/mol
