[Figure not available: see fulltext.] 1-(Adamantan-1-yl)-1H-1,2,3-triazoles and a series of 1-(adamantan-1-yl)-3-alkyl-1,2,3-triazolium salts were synthesized by regioselective adamantylation of 1,2,3-triazole derivatives. The direction of the attack by the adamantyl cation at the N-1 nitrogen atom and the regioselectivity of the processes of adamantylation and quaternization are ensured by a number of factors: the specificity of the properties of the high-acid systems AdOH–HClO4 and AdOH–H2SO4, as well as the structural aspect and high reactivity of adamantan-1-ol.
