Abstract

1, 2, 4-Triazole was alkylated (alkyl= methyl, butyl, heptyl, decyl) at N-1 in> 90% isolated yields. The resulting 1-alkyl triazoles were quaternized at N-4 in> 98% isolated yields using fluorinated alkyl halides with> 98% isolated yields, under neat reaction conditions at 100- 120° C to form N1-CH3-N4-(CH2) 2C m F2 m+ 1-triazolium (Taz) iodide (m= 1, 6), N1-C4H9- N4-(CH2) 2C m F2 m+ 1-Taz iodide (m= 1, 4, 6), N1-C7H15-N4-(CH2) 2C m F2 m+ 1-Taz ...
