Preparation of S<sub>RN</sub>1-Type Coupling Adducts from Aliphatic <em>gem</em>-Dinitro Compounds in Ionic Liquids
Abstract
S<sub>RN</sub>1-type coupling adducts are readily prepared by the reaction between a-sulfonylesters or a-cyanosulfones and <em>gem</em>-dinitro compounds in ionic liquids. The reactions progress smoothly and recovered ionic liquids can be used for several iterations, as long as they are washed with water to remove alkali metallic salts. The reaction rate is slower than the corresponding S<sub>RN</sub>1 reaction in DMSO, but no acceleration on irradiation or no inhibition in the presence of m-DNB are observed.
