T. Miyazawa et al., SELECTIVE CARBON-BROMINE BOND FISSION INDUCED BY NONRESONANT 2-PHOTON(NRTP) EXCITATION OF TRANS-4-BROMOSTILBENE, Chemistry Letters, (5), 1997, pp. 459-460
Non-resonant two-photon (NRTP) excitation of a 1,4-dioxane solution of
trans-4-bromostilbene induces selective homolytic carbon-bromine bond
fission, in contrast to the corresponding single-photon (SP) excitati
on, where the cis-trans isomerization is predominant.
