BF3/nano-sawdust as a green, biodegradable, and inexpensive promoter for one-pot synthesis of tri-substituted imidazoles under solvent free conditions

چکیده مقاله

BF3/nano-sawdust as a green, inexpensive, natural, biodegradable, and readily available biopolymer solid acid catalyst was synthesized and characterized. This catalyst was used successfully for the synthesis of various tri-substituted imidazoles in high yields under solvent free conditions.
