Abstract
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 char ge transfer complexes of 1 and TCNE is a p-anisyl pi-cation radical wh ich then undergoes stereospecific ring opening by C-C bond cleavage.
