  摘要：

  本文介绍了通过微波辐射（MW）方法由相应的环烯基1,2,3-硒代二唑形成一系列的双（环烯基）-1,4-二硒精。1,2,3-硒代二唑的双自由基二聚反应是通过一种新的合成策略在无溶剂条件下使用100瓦特微波辐照约20分钟进行的。当前的合成为制备各种1，4-二硒精提供了可行的方法。如此制备的烷基硒化物通过各种光谱学工具表征。紫外线可见，FTIR，1 H，13 C，DEPT和77Se NMR光谱，ESI-MS和TGA分析。另外，双（环庚烯）-1,4-二硒精已被有效地用作合成CdSe量子点（QDs）的新型硒前体。这种富含硒的前体也可能用于制备其他金属硒化物。

  An efficient solventless synthesis of cycloalkeno-1,2,3-selenadiazoles, their antimicrobial studies, and comparison with parent semicarbazones

  摘要：

  A series of heterocyclic organoselenium compounds, cycloalkeno-1,2,3-selenadiazoles (cyclopenteno, cyclohexeno, cyclohepteno, and cycloocteno-1,2,3-selenadiazoles), was synthesized at room temperature in one step under solventless conditions from the corresponding semicarbazones. The synthesized 1,2,3-selenadiazoles and their parent semicarbazones were screened for their antimicrobial activity against various pathogenic bacteria using agar disc diffusion method. All compounds were found active against E. coli, S. aureus, S. typhi, and P. aeruginosa. Among all the tested selenadiazoles, cyclopenteno-1,2,3-selenadiazole showed excellent inhibition against highly resistant P. aeruginosa. It is observed that selenadiazoles showed higher activity compared with the respective semicarbazones.

  当在130°C下用过量的烯烃处理由环状酮合成的1,2,3-硒代二唑时，会添加乙烯基，该乙烯基是通过1,2,3-硒代二唑进行脱氮而原位生成的。碳-碳双键随后分子内环化有效地进行，从而以中等至良好的收率得到了相应的二氢硒代苯烯，并形成了相应的副产物1，4-二硒代和硒代苯。在该反应中，在1,2,3-硒代二唑的合成中用作起始原料的酮的环上的碳原子数对产物的选择性起着重要作用。与由环状酮制得的1,2,3-硒代二唑的反应相反，在1,2的反应中，

  It was found that the reaction of 1,2,3-selenadiazoles derived from cyclic ketones with olefins or dienes was markedly promoted by a catalytic amount of tributylstannyl radical, which was generated in situ from tributylstannyl hydride or allyltributylstannane and AIBN, to give the corresponding dihydroselenophenes in moderate to good yields. In contrast, when 1,2,3-selenadiazoles prepared from linear
