(Chemical Equation Presented) "Push-pull" phenyltetraene-based chromophores are too sensitive to be incorporated into Diels-Alder-type cross-linkable polymers due to the reactivity of its diene segment with maleimides. A facile synthetic route has been ex

A complex formed by two l,6-anhydro-β-maltoses with peroxide and two sodium ions has been isolated and determined to be [Na2(1,6-anhydro-β-maltose)2(H2O)3]O2 by X-ray crystallography. The O2 moiety, 1.496(2) A for the O-O distances in the complex was identified as a discrete peroxide dianion, whereas two sodium and two carbohydrate molecules constitute a binuclear complex counter cation.The complex containing the discrete peroxide dianion was proven to be a useful oxidizing agent, which successfully oxidized α,β-unsaturated ketone to epoxyketone.
