Abstract
A copper-catalyzed azide–alkyne cycloaddition (CuAAC) reaction for the synthesis of 1,4-disubstituted 1,2,3-triazoles from alkyl diacyl peroxides, azidotrimethylsilane, and terminal alkynes is reported. The alkyl carboxylic acids is for the first time being used as the alkyl azide precursors in the form of alkyl diacyl peroxides. This method avoids the necessity to handle organic azides, as they are generated in situ, making this protocol operationally simple. The Cu(I) catalyst not only participates in the alkyl diacyl peroxides decomposition to afford alkyl azides but also catalyzes the subsequent CuAAC reaction to produce the 1,2,3-triazoles.

Abstract
The 4-arylated pyrimidin-2-yl tosylate derivatives, easily prepared from cheap commercial materials, reacted efficiently with propargyl alcohol/NaOBut to give the corresponding 4-arylated 2-propargyloxy-pyrimidine derivatives which, in a one-pot reaction catalysed by CuSO4·5H2O/sodium ascorbate, reacted with NaN3 and hexyl or benzyl bromide to give a series of 2-(1-hexyl- or 1-benzyl-1,2,3-triazol-4-yl)methoxy-pyrimidine derivatives in good yields.
