Monatshefte für Chemie und verwandte Teile anderer Wissenschaften - Tập 113 - Trang 1469-1473 - 1982
Tóm tắt
Oxidation of 2′-hydroxy-3′-nitrochalcones with thallium(III) nitrate gives (Z)-2-phenylmethylene-7-nitrobenzofuran-3(2H)-one derivatives, rather than the more usual 1,2-diaryl-3,3-dimethoxypropan-1-ones or the corresponding isoflavones.
