Pyrazolyl-functionalized 2-methylimidazolium-based ionic liquids and their palladium(ii) complexes as recyclable catalysts†
Abstract
A series of pyrazolyl- and 3,5-dimethylpyrazolyl-functionalized 2-methylimidazolium-based salts have been prepared through neat reactions of 1-pyrazolylmethylene-2-methylimidazole and 1-(3,5-dimethylpyrazolylmethylene)-2-methylimidazole with
