Abstract A series of fluoroalkylated 1, 2, 3-triazoles have been synthetised in significant yields through unexpected intramolecular cyclisations of vinyl azides bearing electron- withdrawing groups. The mechanism proposed in this study implies the participation of a catalytic amount of azide ions in the cyclisations of the vinyl azides to triazoles. The study includes the alkylation of these compounds with various alkylating agents and the ...
