Abstract
The rates of the competitive photo‐sensitized oxygenation of 2‐isobutylideneadamantane (1) and 2‐propylidene‐adamantane (2) with 1, 1‐di‐t‐butyl‐2‐methoxyethane (3) in various solvents were determined. The rates for 1 and 2 were independent of solvent, whereas that for 3 varied markedly with solvent polarity. Compounds 1 and 2 gave only hydroperoxides while 3 gave dioxetane. These results are interpreted in terms of two competing processes involving little and much charge separation leading to hydroperoxide and dioxetane, respectively.

## Abstract The photo‐oxygenation of 2‐(methoxymethylidene)adamantane (**3**) creates a zwitterionic peroxide which may be captured by acetaldehyde to give the corresponding pair of diastereoisomeric tricyclo[3.3.1.1^3,7^]decane‐2‐spiro‐6′ ‐(3′ ‐methyl‐5′ ‐methoxyl′, 2′, 4′ ‐trioxanes) (**4**). Eas
The absolute quantum yields, QAd, of photosensitized formation of singlet molecular oxygen, O2 (I$), by various sensitizers in benzene were measured by time-resolved thermal lensing (TRTL). Relative measurements with time-resolved O,( 'Ag) phosphorescence detection were used to confirm the absolute
