Thiazolium-ion based organic ionic liquids (OILs). Novel OILs which promote the benzoin condensation.

摘要

4- and 5-methyl thiazole are readily alkylated with n-butyl bromide followed by anion exchange of Br- for BF4- to give mobile, room-temperature ionic liquids. These liquids, when treated with small quantities of triethylamine, serve to promote the benzoin condensation of benzaldehyde. (C) 1999 Elsevier Science Ltd. All rights reserved. [References: 7]
