Study on the Nucleophilic Substitutions of 4,4′-Difluorobenzil with Amines
【摘要】 应用胺类化合物与 4,4′ 二氟苯偶酰的亲核取代反应合成了多种对称或不对称的 4,4′ 双 (二烷氨基 )苯偶酰 .结构经元素分析 ,IR ,1HNMR和MS确定 .其中伯胺与 4,4′ 二氟苯偶酰的反应得到了一边取代、另外一边形成亚胺结构的产物 ,并对此反应机理进行了探讨 .
【Abstract】 Some symmetric and asymmetric 4,4′-bis(dialkylamino)benzils have been synthesized through the nucleophilic substitutions of 4,4′-difluorobenzil with amines. Their structures have been characterized by EA, IR, 1H NMR and MS spectra. When primary amines were employed for the reaction, both the substitution and condensation occured in the substrate molecule. The mechanism of this reaction was discussed as well.
