The syntheses and structures of new classes of unsaturated five-membered heterocycles containing selenium or tellurium and silicon or germanium in the rings prepared on the basis of new heterocyclization reactions of selenium dihalides and tetrahalides or tellurium tetrachloride with the bridged diacetylenes are described. The mechanism of the heterocyclization is discussed.

Keywords: Selenium dihalides, Selenium tetrahalides, Tellurium tetrachloride, Diorganyl diethynyl silanes, Diorganyl diethynyl germanes, Unsaturated five-membered heterocycles
