Abstract:

Valence photoisomerization of endo-tricyclo5.2.1.02,6-deca-4,8- diene-3-one gives a cage structure in quantitative chemical yield and with a quantum efficiency of 0.4 350 nm. The efficiency of storage of electronic excitation energy as chemical potential energy is 8. The photoisomer is thermally quite stable but can be reverted to dienone in the presence of RhI complexes at 140-180C. Catalyst instability prohibits significant recycling of the system. Rate studies bear significantly on the mechanism of RhI catalyzed valence isomerizations.
