Synthesis and characterization of a reactive binuclear co(III) complex. Cooperative promotion of phosphodiester hydrolysis

Abstract A binuclear Co(III) complex has been prepared that shows greater reactivity towards bis(p-nitrophenyl)phosphate than two equivalents of the parent mononuclear Co(III) complex.

A straightforward oxidation of dienones to 2-acetylfurans by selenium dioxide

Abstract Direct oxidation of (E)-4-(6-substituted-1-cyclohexenyl)-3-buten-2-ones (4a–7a) by selenium dioxide afforded 2-acetyltetrahydrobenzofurans (4b–7b) in moderate to good yields. An inverse, stepwise [2+4] cycloaddition mechanism of the intermediate formation was proposed from conformational and electronic requirements of conjugated dienones and solvent effects of SeO2 oxidation.
