Green, new and efficient tandem oxidation and conversion of aryl alcohols to 2,4,6-triarylpyridines promoted by HMImNO3-BMImBF4 as a binary ionic liquid

摘要

A novel, clean and efficient tandem process has been established for the synthesis of 2,4,6-triarylpyridines from primary aryl alcohols or 1-arylethanols using 1-methylimidazolium nitrate in 1-butyl-3-rnethylimidazolium tetrafluoroborate as a binary task-specific ionic liquid under microwave irradiation.
