Comparative study of the catalytic preparation of flavones using Keggin heteropolyacids under homogeneous, heterogeneous and solvent free conditions

Reaction Kinetics, Mechanisms and Catalysis (impact factor: 0.83). 04/2012; 100(1):165-174. DOI:10.1007/s11144-010-0172-4 pp.165-174

ABSTRACT Keggin heteropolyacids are found to be selective and recyclable catalysts for the preparation of flavones. The reaction was
carried out in different reaction media, homogeneous, heterogeneous and solvent-free conditions. The solvent-free conditions
represent the best green conditions.
