, p. 1218 - 1220 (2019/07/16)
A new imidazolium-based poly(ionic liquid) has been synthesized and used as a robust heterogeneous catalyst for the preparation of phenacyl derivatives by an SN2 reaction of different phenacyl bromides with a broad range of nucleophiles. The products are obtained in high yields under mild conditions. The catalyst can be recycled efficiently.
Oxidant-free thiocyanation of phenols and carbonyl compounds under solvent-free conditions by AlCl 3/NH 4SCN

, p. 80 - 88 (2016/02/18)
A simple, efficient, solvent-free, and mild method for thiocyanation of phenols by ammonium thiocyanate (NH4SCN) in the presence of AlCl3 has been developed. This new methodology was used to prepare para-thiocyanated products in good to excellent yields at 70°C. In addition, the successful α-thiocyanation of various ketones has also been described. Finally, a plausible mechanism of thiocyanation has been suggested.
Synthesis of ionic liquid-supported hypervalent iodine reagent and its application as a 'catch and release' reagent for α-substituted acetophenones

, p. 14297 - 14303 (2014/04/17)
A novel imidazolium-based ionic liquid-supported hypervalent iodine reagent has been synthesized and employed for a 'catch and release' strategy with substituted acetophenones to generate various α-substituted acetophenones in good to excellent yields. The use of an ionic liquid-supported hypervalent iodine reagent avoids chromatographic separation for the purification of α-substituted acetophenones and thus makes the method greener.
