Palladium-Catalyzed C–H Arylation of 1,2,3-Triazoles
Molecules, 2016 Palladium(II) acetate, in combination with triphenylphosphine, catalyzes direct arylation of 1,4-disubstituted 1,2,3-triazoles effectively. This C–H arylation reaction provides facile access to fully substituted triazoles with well-defined regiochemistry.

One pot ‘click’ reactions: tandem enantioselective biocatalytic epoxide ring opening and [3+2] azide alkyne cycloaddition [PDF]
, 2010 Halohydrin dehalogenase (HheC) can perform enantioselective azidolysis of aromatic epoxides to 1,2-azido alcohols which are subsequently ligated to alkynes producing chiral hydroxy triazoles in a one-pot procedure with excellent enantiomeric excess.

1,2,4-Triazoles. VII. Methylation of 1,2,4-triazoles.
Chemical and Pharmaceutical Bulletin, 1976 The methylations of twenty-five 1, 2, 4-triazoles with methyl iodide and diazomethane were studied and substituent effects on the product ratios are discussed. Methylation of 1, 2, 4-triazole and its symmetrically 3, 5-disubstituted derivatives occurred almost exclusively at the 1-position.
