The photochemistry of 1-(o-methylphenyl)-2,2-dimethylpropane-1,3-diones 4 has been investigated.Compounds 4a-h underwent photocyclization to give benzocyclobutenols 11a-h and naphthalenones 12a-h in hexane or methanol.Compound 4i gave the naphthalenone 12i in methanol.The product ratio 11:12 was greater in hexane than in methanol.This ratio increases with chain branching of the C-3 substituent R and with increasing size of R.Compounds 4a, b and d gave isobutyrophenones 13a, b and d along with products 11 and 12 in hexane.
