Photolysis (>350 nm) of (2-phenoxyphenyl)phenyldiazomethane (1)in cyclohexane at 10 °C gave the title compound (4), while similar irradiation with a shorter wavelength light (>300 nm) afforded a mixture of the isomers (5–7), which were shown to be formed by photoisomerization of the initially formed 4.
