1-Alkyl-3-methyl-1,2,3-triazolium [NTf2] ionic liquids: synthesis and properties
摘要:
A series of 1-alkyl-3-methyl-1,2,3-triazolium bis(trifluoromethylsulfonyl)imide [NTf2] ionic liquids were prepared synthetically using azide-alkyne 'click' cyclization chemistry and their physicochemical and thermal properties were determined. Increasing the alkyl chain length resulted in increased viscosities and higher thermal transitions (T-g or T-m) with depressed molar conductivities. Walden plot analysis indicated that the Tonicity of 1-butyl-3-methyl-1,2,3-triazolium [NTf2] was comparable to the analogous imidazolium system and higher than the 1,2,4-triazolium equivalent.

This paper details a simple and efficient 3-component synthesis of 1-substituted 1,2,3-triazoles using a primary amine, 2,2-dimethoxyacetaldehyde and tosylhydrazide. The reaction proceeds in good to excellent yields using either aliphatic or aromatic amine substrates and is tolerant of a wide range of functional groups including electron-rich and deficient aryl groups, terminal alkynes, ketones and

Two-step one-potreaction conditions have been developed for synthesizing 1-substituted-1,2,3-triazoles. This transformation involves the base-catalyzed deprotection of trimethylsilylacetylene followed by Cu-catalyzed Huisgen 1,3-dipolar cycloaddition under aqueous reaction conditions. Utilization of potassium carbonate as the base and methanol as the alcoholic aqueous co-solvent resulted in optimal
