In dilute ethanol or tertiary butanol solutions irradiated
with light of wavelength 300 nm, 1:1', 3:4-diepoxy-1-methyl-2-
tetralone (I) was found to rearrange to the phenols (III) and (XIX) and
to the pyrone (XXI). The identities of (XIX) and (XXI) were confirmed
by synthesis whilst the identity of (III) was confirmed by comparing
its properties with those of an authentic sample. Possible
rearrangement mechanisms leading to the formation of these products
are described.
