An efficient synthesis and biological activity of substituted p-benzoquinones.

An efficient synthesis of 2,5-diarylamino-3,6-dichloro-1,4-benzoquinone derivatives has been achieved by condensing mono substituted anilines with tetrachloro-p-benzoquinone in presence of fused sodium acetate as condensing agent under microwave irradiation without any solvent. All the synthesized compounds were tested for their antibacterial and antitumour activity using standard drugs.
