Basic Task-specific Ionic Liquid as Catalyst and Reaction Medium: A Green Protocol for the Synthesis of 4-Oxo-6-aryl-2-thioxo-1,2,3,4- tetrahydropyrimidine-5-carbonitrile Derivatives
Abstract A novel basic ionic liquid based on imidazolium cation is designed, synthesized and successfully used as a catalyst for the one-pot synthesis of 4-Oxo-6-aryl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile derivatives. The remarkable features of this new catalyst are its ethyleneoxy bridge which participates in dissolving organic compound in the ionic liquid and its strong base co...
متن کاملEco-Friendly and One-Pot Synthesis of 1,8-Dioxooctahydroxanthene Derivatives Catalyzed by Task-Specific Brønsted Acidic Ionic Liquid
Efficient and one-pot synthesis of 1,8-dioxo-octahydroxanthenes was described by Knoevenagel condensation, Michael addition and cyclodehydration of dimedone. This reaction was carried out through condensation of dimedone and various aromatic aldehydes in the presence of task-specific Brønsted acidic ionic liquid under solvent free conditions. The catalyst could be recycled five times without si...
متن کاملCO(2) capture by a task-specific ionic liquid.
Reaction of 1-butyl imidazole with 3-bromopropylamine hydrobromide, followed by workup and anion exchange, yields a new room temperature ionic liquid incorporating a cation with an appended amine group. The new ionic liquid reacts reversibly with CO2, reversibly sequestering the gas as a carbamate salt. The new ionic liquid, which can be repeatedly recycled in this role, is comparable in effici...
