Novel Acid-catalysed Rearrangement of 4-Substituted Pentacyclo2,5.03,9.04,8>decan-6-ones; X-Ray Molecular Structure of 1-Phenylpentacyclo2,10.03,8.05,7>decan-4-one

4-Substituted pentacyclo2,5.03,9.04,8>decan-6-one derivatives 2a and b undergo a novel acid- or Ag+-catalysed rearrangement to the hitherto unknown pentacyclo2,10.03,8.05,7>

Photochemistry of 5-Phenyltricyclo2,6>deca-4,8-dien-3-one: Upper Singlet Excited State Involved in Intramolecular Photocycloaddition and Long-lived Triplet Excited State in Photodimerisation

Upon ?,?(excit.) excitation, 5-phenyltricyclo2,6>deca-4,8-dien-3-one predominantly undergoes intramolecular photocycloaddition probably via the higher singlet excited state (S2), while, upon n,?(excit.) excitation, it undergoes predominantly photodimerisation via a relatively long-lived triplet excited state.
