 Abstract: Z‐diazocine, synthesized as described by Tellkamp[1], has been photochemically converted into E‐diazocine by irradiation of its solution at λ=365 nm. After purification, single crystals of E‐diazocine were obtained by recrystallization at −18 °C from n‐pentane. The title compound was characterized by NMR spectroscopy and X‐ray crystallography. For its thermal isomerization into the more stable Z‐isomer, the thermal half‐life was determined by UV/Vis absorption studies. Furthermore, the photochemical behaviour of the compound in the solid state has been investigated.
