Triphenylpyrylium salt sensitized photoreactions of several dithianes and dithiolanes produced carbonyl compounds in good yields in the presence of molecular oxygen. Molecular oxygen trapping of carbon radical intermediates generated through selective C-S bond cleavage of dithiane and dithiolane cation radicals is proposed.
