Results Thioketones 1-11 investigated are listed in Figure 1. Finely pulverized crystals of 2- 11 were exposed to UV radiation in aerated atmosphere in Pyrex petri dishes. Several of these thioketones readily changed their color and were converted quantitatively to the corresponding ketones; no other products were identified. Surprisingly, some of these thioketones were found to be stable to UV radiation under these conditions. Results are ...
