Abstract: Benzophenone oxide has been shown to oxidize 1-chloronaphthalene and p- xylene with accompanying NIH shift of chlorine and methyl, respectively. Similar oxidation of toluene leads to a mixture of 0-, p-, and m-cresols while N-acetyl-L-phenylalanine ethyl ester is oxidized to the corresponding tyrosine derivative. The results are discussed in terms of their relationship to the" activation" of polycyclic aromatic hydrocarbons in polluted ...
