1-Allyl- and 1-Benzyl-3-methyl-1,2,3-triazolium Salts via Tandem Click Transfor-mations. — Triazoles of type (III) are synthesized in a one-pot manner via 1,3-dipolar cycloaddition of terminal alkynes bearing an alkyl chain and organic azides, generated in situ. Methylation yields triazolium iodides which are viscous liquids with stable shelf life. Triazoles resulting from sterically hindered alkynes (R1:-tBu or -Ph) reveal only marginal conversion to the salts. — (FLECHTER*, J. T.; KEENEY, M. E.; WALZ, S.
