5-methyl thiazole undergoes alkylation with n-butyl bromide followed by anion exchange of Br- for BF4- to yeild mobile, room-temperature ionic liquids. | [General Description]
The microwave spectrum of 5-methylthiazole was investigated by employing both Fourier transform and Stark spectroscopy. 5-methyl thiazole undergoes alkylation with n-butyl bromide followed by anion exchange of Br- for BF4- to give mobile, room-temperature ionic liquids. |
