In aceptone solution u.v. irradiation of isobenzofuran at –60 °C forms an [8 + 8] dimer shown by lanthanideinducedshiftspectroscopy to have the anti-stereochemistry; in ether solution an [8 + 8] dimer is obtained together with a skeletally modified dimmer, the structure of which is confirmed by synthesis.
