N-(Benzotriazol-1-ylmethyl)-indole, - pyrrole, -carbazole, and -benzimidazole, and analogs substituted in the methylene group are converted by lithium aluminum hydride, or by Grignard reagents, or in two cases by organozinc reagents, into the N-substituted heterocycles in good yields.
Base-catalyzed rearrangement of α-benzotriazolyl alkoxide anions: Synthesis of one-carbon homologated α-substituted alkyl ketones

Deprotonated benzotriazole derivatives (1a-c) reacted with aldehydes to give the α-oxyanion substituted intermediates (2), which upon further treatment with butyllithium, without separation, resulted in the formation of one-carbon homologated α-substituted alkyl ketones (6a-f). Similar treatment of benzotriazole derivatives (1d-f) generated the benzotriazole ring-opening and rearranged products (7a-f). Plausible mechanisms for these reactions have been proposed.
