A Novel Synthesis and antimicrobial activity of Flavanone Using environmental friendly Catalyst H(bimBF4)

A high yielding and fast method for smooth conversion of substituted α-β-unsaturated carbonyl compounds (E) chalcones to corresponding substituted 2-phenylchroman-4-one i.e. flavanone by grinding at room temperature using ionic liquid H[bimBF4] .which is recyclable . Flavanone was synthesized and tested for antibacterial effects against Bacillus Subtalis, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa.. The antibacterial screening of the synthesized compounds were performed in vitro by the filter paper disc diffusion method.
