Methylene-bridged bis-1,3-dicarbonyl derivatives were synthesized efficiently by iron-catalyzed oxidative reactions of 1,3-dicarbonyl compounds and N,N-dimethylaniline. Bipyrazoles and substituted 1,4-dihydropyridine were obtained by the reactions of bis-1,3-dicarbonyl compounds with hydrazines and ammonium acetate, respectively.
亚铁桥联的双1,3-二羰基衍生物是通过铁催化的1,3-二羰基化合物与N,N-二甲基苯胺的氧化反应而有效合成的。联吡唑和取代的1,4-二氢吡啶分别通过双-1,3-二羰基化合物与肼和乙酸铵的反应制得。
