bis‐ketones/bis‐esters/bis‐keto esters with dimethyl diazomalonate and ethyl diazoacetate were studied. Total steric/electronic convenience of the present reaction paths was investigated. Methoxy/nitro substituents in m‐/p‐positions on benzylidene biscarbonyls did not alter the general routes of the reactions, supporting concerted mechanism. Dihydrobenzoxepine/oxepine formation was sterically sensitive

New β-diketone phenylhydrazones prepared by condensation of substituted 3-arylidene-2,4-pentanediones with phenylhydrazine, have been characterized by their elemental analyses, IR, 1H NMR, and mass spectra. Some complexes of these Schiffbases with Co(II), Ni(II), and Cu(II) ions have been synthesized; in addition to the above methods, their structures were studied by magnetic susceptibility and thermogravimetry
通过取代的3-亚芳基-2,4-戊二酮与苯肼缩合制备的新型β-二酮苯hydr已通过其元素分析,IR,1 H NMR和质谱进行了表征。已经合成了这些 席夫 碱与Co(II),Ni(II)和Cu(II)离子的一些配合物 。除上述方法外,还通过磁化率和热重分析法研究了它们的结构。
