The mechanistically interesting claim was recently made that the dyesensitized photo-oxygenation of biadmantylidene (1) in pinacolone as solvent gave the corresponding dioxetane (2) and epoxide (2) while solvent was converted to t-butyl acetate.' This result was interpreted as proof that a perepoxi
The oxidative decarboxylation of a-ketoglutaric acid by molecular oxygen is thought to be the key step in several dioxygenase-catalyzed hydroxylations.' In general, a-ketocarboxylic acids are unreactive towards ground-state molecular oxygen. However, we have reported that singlet oxygen, generated b
