Naphthalene was phenylated with phenyl cation (from PhN<SUB>2</SUB>BF<SUB>4</SUB>) or phenyl radical (from PhN<SUB>2</SUB>BF<SUB>4</SUB>+NaNO<SUB>2</SUB>) in dimethyl sulfoxide. Partial rate factors for phenyl radical were somewhat larger than those reported with the phenyl radical generated from <I>N</I>-nitrosoacetanilide. Partial rate factors for phenylation with phenyl cation were smaller than those for free radical phenylation and those for common electrophilic substitution reactions. These small partial rate factors for phenyl cation were not compatible with the reaction scheme involving an ordinary σ-complex, and a mechanism involving a spiro cation appeared to be plausible.
