Starting with 1,5-cyclooctadiene (1), the title compound 9 is gained in a synthesis of seven steps. 9 exists in two conformations 9a and 9b, of which 9a shows a strong interaction between the oxygen atom and the strained triple bond.Thermal fragmentation of the 1,2,3-selenadiazole 7 is used for the introduction of the triple bond.The structural proof of 7 is performed by 2D-NMR spectroscopy.
