Phenylnitrenium cation

The phenylnitrenium cation (PhNH+), formally generated upon ionization of the anilino radical, exhibits a singlet ground state ( A ), followed by a triplet state (3A"), with a singlet-triplet energy gap of AESt(P1iNH+) = 0.84 0.1 eV (81 kJmol-1)210,211. [Pg.128]

An AMI study of the mechanism of the reaction between the free phenylnitrenium cation and benzene is reported. It has been found that both syn and anti conformations of arylnitrenium ions are possible, and that the two are separated by substantial... [Pg.325]

The products isolated upon photolysis of phenyl azide 10 in addic medium agree with this description. At low pH (aq. HCl), o- andp-chloroaniline 113 and 114 and 4-aminophenol 115 were among the main products. All of these products can be rationalized in terms of cyclohexadienyl-cation-type reactivity of the phenylnitrenium ion. Aminophenol 115 is formed via the iminocyclohexadienol 116, which was... [Pg.870]
