4‐Bromomethylcoumarins, prepared by the reaction of phenols and 4‐bromoethyl acetoacetate, were reacted with primary aromatic amines to yield 4‐anilinomethylcoumarins. The spectral properties and antimicrobial activities against five micro‐organisms are reported.

A series of new fluorinated coumarins and 1-aza coumarins have been synthesized and the presence of fluorine in these molecules and its effect on their anti-microbial, anti-inflammatory and analgesic activities are discussed. The results of bioassay showed that these newly synthesized compounds containing fluorine exhibit moderate analgesic and excellent anti-inflammatory and potential anti-bacterial
