Catalytic Activity in the Reversion of an Energy Storing Valence Photoisomerization

Abstract

Valence photoisomerization of endo-tricyclo(5.2.1.0(2,6))-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 Rh(I) complexes at 140-180C. Catalyst instability prohibits significant recycling of the system. Rate studies bear significantly on the mechanism of Rh(I) catalyzed valence isomerizations.
