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.
Reactions of N-Alkyl-N-phenyl-1H-benzotriazole-1-methanamines with α,β-Unsaturated Ethers. A Novel Route to 1,4- and 1,3-Disubstituted 1,2,3,4-Tetrahydroquinolines

N-Alkyl-N-aryl-1H-benzotriazole-1-methanamines 3, easily accessible from the condensation of anilines with formaldehyde and benzotriazole, undergo acid-catalyzed reactions with ethyl vinyl ether to give 1-alkyl-4-(benzotriazol-1-yl)-1,2,3,4-tetrahydroquin
