1-Ethyl-3-methylimidazolium halogenoaluminate ionic liquids as reaction media for the acylative cleavage of ethers

2‐Arylhydroxynitroindoles: A new procedure for the cleavage of aryl methyl ethers

“…Two researches formally not related to our case prompted us the solution of this problem. The authors of the first article [11] emphasize the impact of ionic liquids as high polar media on the cleavage of ethers under the action of benzoyl chloride. The second [12] examines transesterification of methyl esters of carbonic acids as affected by tetraalkylammonium halides to produce corresponding alkyl esters and points out that the tertiary ammonium salt melt used without any solvent is optimal for the reaction.…”

Structural Effects on the Physico‐Chemical and Catalytic Properties of Acidic Ionic Liquids: An Overview

“…[96] Their extensive deployment in Friedel-Crafts reactions notwithstanding, Lewis acidic ILs have also been applied in many other processes. 1-Ethyl-3-methylimidazolium iodide/ AlCl 3 (AlCl 3 /emimI ratio Ͼ 1:1) has been used with success in acylative cleavage of ethers, [97] whereas other imidazolium or pyridinium chloroaluminates have been applied in coumarin syntheses through Pechmann condensations of phenols with ethyl acetoacetate, [98] Knoevenagel condensations, [99] or oligomerizations [100] or dimerizations [101] of olefins, or as alternative media for syntheses of 4-chloropyrans through Prins reactions. [102] Moisture-stable Lewis acidic ILs have also been employed as alternative media in other Lewis-catalyzed reactions.…”

Ionic Liquids within Microfluidic Devices

“…Ionic liquids have been thoroughly investigated as (co)solvents in most types of catalytic reactions such as rhodium and ruthenium catalyzed hydrogen addition and rearrangement reactions (Chauvin et al, 1995;Dyson et al, 1999), C-C and C-O cleavage reactions (Green et al, 2000;Song et al, 2000), and C-C or C-heteroatom coupling reactions (Earle et al, 1999;Zulfigar & Kitazume, 2000). In these reaction systems, ionic liquids can be used as solvent or both solvent and catalyst in monophasic systems.…”
