Abstract
A series of para-substituted aromatic aminonitrones p-RC6H4C(NH2)=N+(Me)O– (R = NMe2, H, Br, Cl, CF3) have been prepared. Acidity constants of the conjugate acids RC6H4C(NH2)N+(Me)OH at 25°C in a EtOH–H2O mixture (5: 95) have been determined by potentiometric titration. A linear correlation between log (kR/kH) and σpara values has been revealed, and a ρ298(σpara) parameter has been determined as of 0.635.
