Silica-Supported Antimony(III)Chloride as an Efficient Heterogeneous Catalyst for the Synthesis of Aminopropenones and 3-Aminopropenoates under Solvent-Free Conditions

摘要

A convenient and efficient procedure has been developed for the synthesis of 3-aminoprop-2-en-1-ones and 3-aminoprop-2-enoates catalyzed by silica-supported antimony(III)chloride at room temperature under solvent-free conditions.The reaction takes a short time and ensures good to excellent yields of the products.Both aromatic and aliphatic amines and various 1,3-dicarbonyl compounds,including beta-ketoesters and beta-diketones,can be involved.
