A series of novel 3-phenylnorbomadienes with conjugated substituents i
n 2-position (carbaldimine, carbaldoxime, amide, aroylvinyl and hetero
cyclic groups) have been synthesized. All the compounds obtained absor
b in the 310-420 nm spectral region and under UV-Vis-irradiation form
corresponding quadricyclanes with quantum yields in the range of 0.1-0
.7. The back reaction proceeds almost quantitative yield under homogen
eous and heterogeneous catalysis or on heating.
