Notes:
The 1H NMR technique was applied for the measurement of the isomerization rates of N-ethyl-N-[(benzotriazol-1-yl)methyl]aniline (4) and 4-butyl-N-[(benzotriazol-1-yl)methyl]aniline (7) to the corresponding benzotriazol-2-yl isomers in dioxane-d8 at 35°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 to 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. © 1995 John Wiley & Sons, Inc.
