cycloalkeno-1,2,3-selenadiazoles by a microwave irradiation (MW) method. The bi-radical dimerization reaction of 1,2,3-selenadiazoles was performed by a new synthetic strategy under solvent-free conditions using 100 Watt microwave irradiation for about 20 minutes. The current synthesis afforded a feasible approach for the preparation of various 1,4-diselenins. The so-prepared alkyl selenides were characterized
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。
