Abstract

The behavior on lithiation of seventeen N-substituted benzotriazoles was investigated. In seven cases, the N-substituent was either removed or no lithiation occured, in six instances lithiation occurred in the N-substituent and in the four remaining compounds lithiation occurred at the ring 7-position, albeit in low yield.
