The photosensitized reductions of 4-cyanobenzylmethylphenyl sulfonium tetrafluoroborate (1-BF4) by 9-phenylanthracene, 2-ethyl-9,10-dimethoxyanthracene, or perylene excited singlet states gives quantitative yields of phenyl methyl sulfide. Fluorescence quenching and the quantum yields for product formation, as functions of [1-BF4], give bimolecular rate constants (0.58−1.6 × 1010 M-1 s-1) for reaction
