Photochemistry of halogenated benzene derivatives. I. Trichlorobenzenes : reductive dechlorination, isomerization and formation of polychlorobiphenyls

Abstract Irradiation of the three trichlorobenzenes with λ > 285 nm in a few solvents results in reductive dechlorination as the major reaction, and isomerization and formation of polychlorobiphenyls in some cases.
