【Abstract】 Objective: A series of novel substituted benzaldehyde diamines Schiff bases were synthesized for screening antibacterical agents. Methods: The Schiff bases were prepared by the condensation reaction of substituted benzaldehyde with diamines. Their antibacterial activities were tested. Results: Eight novel Schiff bases were synthesized and their structures were identified by elementary analysis, IR spectra and H 1NMR. Conclusion: The synthetic Schiff bases have displayed significant antibacterical activities.更多还原
