V. Singh et B. Thomas, Studies on photoreaction of endo-tricyclo[5,2,2.0(2,6)]undecadienones in excited singlet state, J INDIAN CH, 75(10-12), 1998, pp. 640-644
Photochemical reaction of endo-tricyclo[5.2.2.0(2,6)]undecadienones 1-5 and
8, 9 upon singlet excitation her been investigated. A novel photodecarbony
lation has been observed.
