IV. CONCLUSION
Microwave-assisted synthesis is a convenient way toward the goal of green chemistry. Highly substituted, 2, 5-Dianilino-3, 6Dichloro-1, 4-Benzoquinones (3a-d), have been synthesized .Mass fragmentation of the title compounds along with m/z values and relative intensity of the fragment and 13C NMR characterize the derivatives of 2, 5-Dianilino-3, 6-Dichloro-1, 4-Benzoquinones.
