Friedel–Crafts alkylation of 4-hydroxycoumarin catalyzed by sulfonic-acid-functionalized pyridinium chloride as a new ionic liquid
Comptes Rendus Chimie Vol. 17, No. 12, 1264–1267
چکیده
A green, simple and efficient synthesis of bis-coumarin derivatives via the condensation of 4-hydroxycoumarin with arylaldehydes using sulfonic-acid-functionalized pyridinium chloride {[Pyridine–SO 3 H]Cl} as a new, homogeneous and reusable catalyst and ionic liquid is reported.
