DIRECT PHOTOLYSIS AT 185 NM OF CYCLOPENTENE AND 2-NORBORNENE. A NOVEL REACTION CHANNEL FOR π,π* EXCITED SINGLET ALKENE
Upon direct irradiation at 185 nm, the title compounds undergo hydrogen abstraction from the solvent via a π,π* excited singlet state as well as skeletal rearrangement via a π,R(3s) Rydberg excited state.
