The 1H NMR technique was applied for the measurement of the isomerization rates of N-ethyl-N-aniline (4) and 4-butyl-N-aniline (7) to the corresponding benzotriazol-2-yl isomers in dioxane-d8 at 35 deg C.The rate constants obtained for pure dioxane-d8 were 1.62 and 0.28 h-1 for 4 and 7, respectively.For both compounds, addition of acetic acid to the dioxane solutions accelerated the isomerizations whereas addition of triethylamine retarded it strongly.Addition of water slowed the isomerization of 4 but accelerated that of 7: the different effects operating in the two cases are discussed and rationalized.

1-(Hydroxymethyl)benzotriazole and aromatic amines react to give an equilibrium mixture of N-mono- and N,N-bis(benzotriazolylmethyl)arylamines.Electron-releasing substituents on the arylamine ring shift the equilibrium towards the N,N-bis(benzotriazolylme
