The mechanism for the photocycloaddition of tetraarylthiiranes 1 with TCNE was probed by stereochemical and spectroscopic studies. Evidence is presented that the cation radical formed on irradiation of the charge transfer complexes of 1 and TCNE is a p-anisyl π-cation radical which then undergoes stereospecific ring opening by C-C bond cleavage.
