Butadiene, cycloocta-1,5-diene and cycloheptatriene were found to form cycloaddition products with 2,5-bis(perfluoroalkyl)-1,3,4-oxadiazoles: 3-oxatricyclo[2.2.1.02,6]heptane, 7-oxatetracyclo[6.3.0.02,6.05,9]undecane and 6-oxatetracyclo[5.3.0.02,5.04,8]dec-9-ene, respectively. The structure of the last compound was confirmed by single crystal X-ray diffraction.
