Jain, Auteur ; Sweety Singhal, Auteur Année de publication : 2011 Article en page(s) : pp. 11463-11466 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Dihydropyrimidinones Tetrachloroindate Résumé : 1-n-Butyl-3-methylimidazolium tetrachloroindate (BMI·InCl4) was found to be an efficient catalyst for the synthesis of 3,4-dihydropyrimidinones in high yields under solvent-free conditions. The recovered ionic liquid phase could be reused for several runs without significant loss in activity. In addition, BMI·InCl4 is more stable toward water and air than its analogous 1-n-butyl-3-methylimidazolium tetrachloroaluminate and, hence, easier to handle.
