With raw materials of benzoyl chloride and p-bromophenol, mono-Schiff base, 2-[(2-aminophenylimino) phenylmethyl]-4-bromophenol,is obtained through multi-step reactions of esterification,Fries rearrangement and condensation. The mono-Schiff base reacts with aldehydes and ketones to give five asymmetric di-Schiff bases and two symmetric di-Schiff bases. These Schiff bases,particularly those containing sulfur atom in the molecule,show good antibacterial activities with a minimum inhibitory concentration of 1×10-4g/L.
