Abstract:

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.

 

Key words: Schiff base, synthesis, rearrangement, antibacterial activity
