1,2-Diarylethanes and 1,2-diarylethylenes can be oxidized directly to 1,2-diaryldiketones in good yields by reaction with benzeneseleninic anyhdride (BSA) at 120 °C in chlorobenzene.
dibenzocyclooctendiones (DBCDOs) are efficient chemical reagents for the site-specific labeling of arginine-containing biomolecules. Unlike the commonly used probes, DBCDOs undergo an irreversible ring-contracted rearrangement with the guanidinium group on arginineresidues under mild reaction conditions. The regioselective dual-labeled arginineresidues were obtained in a one-pot reaction with our tested
