Efficient Reaction Between Substituted 2-Acetyl-1-Naphthol/2-Acetyl-1-Naphthol and Different Substituted Benz Aldehydes |
we have developed a simple,efficient and more eco-friendly method for synthesis of chalcones by grindingtechnique. The notable advantages of present method are no organic solvent required (except for the product recrystallization), wasteminimization, simple operation, clean reaction profile, easy work-up, shorterreaction time (4-8 min.), high yields (84-95 %) and eco- friendly as comparedto conventional method.
