Synthesis of Isomeric N-Adamantyl Derivatives of 4-Phenyl- And 4,5-Diphenyl-1,2,3-Triazoles

1-Adamant-1-yl-4-phenyl-1H-1,2,3-triazole and 2-adamant-1-yl-4,5-diphenyl-2H-1,2,3-triazole were synthesized by alkylation in strong proton acids as well as by 1,3-dipolar cycloaddition. It was shown that the regioselectivity of the interaction of NH-unsubstituted 1,2,3-triazoles with the carbonium ion has been determined by the presence and nature of the substituent at the endocyclic carbon atoms
