| Abstract: | Cycloalkeno-1,2,3-selenadiazoles can be prepared from cycloalkanone-semicarbazones with SeO2. Pyrolysis yields bis-cycloalkeno-1,4-diselenines and cycloalkynes, which can be trapped with tetraphenyl-cyclopentadienone. A detailed spectroscopic characterization of the 1,2,3-selenadiazoles and the 1,4-diselenines is given. |
