These studies have recently been extended to the naphthalene system.(142) In alkaline media 2-methoxy-5-nitro-, l-methoxy-6-nitro-, and 2-methoxy-7-nitro-naphthalenes all undergo photosubstitutions to produce naphthols ... [Pg.276]

The pH dependence of the regioselectivity for the nucleophilic photosubstitution of 3,4-dimethoxy-l-nitrobenzene by n-butylamine gives21 2-methoxy-5-nitro-Af-butylaniline as the major product at pH = 11 (equation 19). At pH = 12, the ratio of the major product to 2-methoxy-4-nitro-7V-butylaniline increases to 12 1 the increased selectivity is caused by hydroxide ion, which can either promote exciplex formation or act as a base catalyst in deprotonation steps following the cr-complex formation22.
