Mechanistic studies on the photogeneration of o- and p-xylylenes from α,α′-dichloroxylenes

Abstract

Two-colour two-laser techniques have unambiguously proved that photolysis of the o-/p-(chloromethyl)benzyl radical leads to the sequential two-photon generation of o-/p-xylylene from α,α′-dichloro-o-/p-xylene.
