Abstract

Abstract The synthesis of 1-[(2-Ro-carboran-1-yl) methyl] benzotriazoles (R= Me, Ph) is described. α-Deprotonation of these compounds followed by reactions of the generated carbanions with MeI give the corresponding α-methylated products. Even at room temperature, they exist in solution as an equilibrium mixture of two conformers due to steric crowding around the C α atom. In contrast, the anions generated by deprotonation of α- ...
