In this paper, thiosemicarbazone derivatives have been prepared from substituted aromatic aldehyde and thiosemicarbazide in presence of sodium chloride. This method is an efficient, mild, inexpensive, non-toxic and environment benign catalyst. This protocol includes the reaction followed by using sodium chloride to accelerate the reaction in aqueous ethanol. The structure of synthesized compounds were determined by IR, 1H NMR, 13C NMR and mass spectroscopies as well as the compounds were also screened for antibacterial and antifungal activity against certain Gram-negative and Gram-positive bacteria and fungal pathogens.
