-9,18-Dimethyl-2,11-diselena[3.3]metacyclophane - a correction to the literature. The selenoxide elimination applied to the synthesis of dimethyldihydropyrene.

Abstract The previously reported title compound was incorrect. The now obtained sample was characterised by X-ray structure determination, 1 H and 13 C nmr spectra and via a selenoxide elimination into the known 15,16-dimethyldihydropyrene.
