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 (benzotriazolylmethylated) products, and removal of water formed in the reaction leads to these bis derivatives in quantitative yields. These products were isolated as mixtures of three isomers, the ...
