What is Synthesis of New Heterocycles Containing More Than One 1,2,3-Thia or Selenadiazole Rings about?
## Abstract magnified image The diketones **2a‐d** with different alkyl chain length are used for the synthesis of di‐1,2,3‐thia or selenadiazole derivatives **4a‐d** and **5a‐d**. The diketones **2a‐d** where prepared by a unique method through the reaction between the corresponding dibromoalkanes **1a‐d** and ethyl acetoacetate, which are transformed into the corresponding semicarbazone derivatives **3a‐d**. The di‐1,2,3‐thia or selenadiazole derivatives **4a‐d** and **5a‐d** were prepared from the semicarbazones derivatives **3a‐d** on oxidative cyclization with thionyl chloride and selenium dioxide respectively in high yield.
