In the current work, a series of mono-fluoroalkylated [1,2,3]-triazole precursors was prepared by the 1,3-dipolar cycloaddition reaction of allyl azide and perfluoroalkylethoxyl propynes, in which the CuSO4 and sodium ascorbate were used as the catalyst. Using these precursors as unsaturated substrates, a series of novel mono-fluoroalkyldichloromethyl silanes were successfully synthesized via hydrosilylation between CC and Si-H bonds. Furthermore, to construct fluorosilanes with two or more stacked fluoroalkyl groups in one molecule, silanes with bis-fluoroalkylated [1,2,3]-triazoles as pendants were synthesized afterwards.
