An efficient methodology for the synthesis of bis[3-(4-chloro-N,N-diethylpyridine-2-carboxamide)] diselenide has been successfully achieved through ring lithiation using 2.2 equivalents of lithium diisopropylamide (LDA) in THF. The hitherto unknown compound has been fully characterized by spectroscopic techniques NMR (¹H and ¹³C), Mass spectrometry and elemental analysis. The crystal structure of bis[3-(4-chloro-N,N-diethylpyridine-2-carboxamide)] diselenide has been determined by single crystal X-ray diffraction. The diselenide crystallizes in the monoclinic system (C2/c) with torsional angle of the selenium atoms attached to pyridyl rings (-C₁–Se–Se–C₁-) is −77.5(1). Bis[3-(4-chloro-N,N-diethylpyridine-2-carboxamide)] diselenide was found antibacterial active and results were compared with the most studied pyridylselenium compound (2,2′-dipyridyl diselenide) and standard drug Ampicillin.

使用 2.2当量的二异丙基氨基锂 (LDA) 在 THF 中通过环锂化成功实现了合成双 [3-(4-氯-N,N-二乙基吡啶-2-甲酰胺)] 二硒化 物的有效方法 。迄今为止未知的化合物已通过光谱技术 NMR（¹ H 和¹³ C）、质谱和元素分析进行了充分表征。 双[3-(4-氯-N,N-二乙基吡啶-2-甲酰胺)]二硒化物的晶体结构已通过单晶X射线衍射确定。二硒化物在单斜晶系 (C2/c) 中结晶，其中硒原子的扭转角与吡啶环 (-C ₁ –Se–Se–C ₁-) 是 -77.5(1)。双[3-(4-氯-N,N-二乙基吡啶-2-甲酰胺)]二硒化物被发现具有抗菌活性，并将结果与​​研究最多的吡啶基硒化合物（2,2'-二吡啶基二硒化物）和标准药物氨苄青霉素进行比较。
