摘要:
Syntheses and antimicrobial behavior of the alkyl linked new bispyrazolines 4a, 4b, 4c, 4d, 4e, 4f, 4g have been investigated. These compounds exhibited better antimicrobial activities as compared with their corresponding bischalcones. The structures of the prepared compounds (3a, 3b, 3c, 3d, 3e, 3f, 3g and 4a, 4b, 4c, 4d, 4e, 4f, 4g) were determined from the rigorous analysis of their IR, 1H NMR, 13C NMR, and mass spectral parameters.
