Benzotriazolyl hydrazide (2) has been obtained from the ester ethyl benzotriazolyl acetate (1). The hydrazide with various aromatic aldehydes in presence of glacial acetic acid gave corresponding arylidenes 3(a-h). The arylidenes were made to react with fluoro substituted diazonium salt whereby, benzotriazolyl formazans 4(a-h) were obtained. The structures of the compounds were confirmed by FTIR, 1 H-NMR, mass spectral data and elemental analysis. All the synthesized compounds were screened for their in-vitro antimicrobial activity against the bacterial strains Bacillus subtilis and Escherichi

In the case of salicyaldehyde the reaction lead to the formation of 3-substituted coumarins.
