Green Synthesis of 2-Oxazolidinones by an Efficient and Recyclable CuBr/Ionic Liquid System via CO2, Propargylic Alcohols, and 2-Aminoethanols

چکیده
With the aim of profitable conversion carbon dioxide (CO2) in an efficient, economical, and sustainable manner, we developed a CuBr/ionic liquid (1-butyl-3-methylimidazolium acetate) catalytic system that could efficiently catalyze three-component reactions propargylic alcohols, 2-aminoethanols, CO2 to produce 2-oxazolidinones ?-hydroxy ketones. Remarkably, this employed lower metal loading (0.0125–0.5 mol%) but exhibited highest turnover number (2960) ever reported, demonstrating its excellent activity sustainability. Moreover, our work under 1 atm pressure recycle among metal-catalyzed systems.

CdO nanoparticles as an efficient, mild and recyclable catalyst for the synthesis of 2-aryl benzoxazole derivatives by grinding method
CdO nanoparticles efficiently catalyzes the condensation of aromatic aldehydes with 2-aminophenol at room temperature to afford 2-aryl benzoxazole derivatives by grinding method. The reactions proceed under heterogeneous and mild conditions to provide 2-aryl benzoxazoles in excellent yields (87-97 %) with high purity under solvent free condition. The reaction requires short time (5-23 minutes) ...
