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.

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
