Photolysis of methyl yl-1,4-dihydro-1,4-ethenonaphthalene-3-carboxylat
e (4) produces two di-pi-methane photoproducts m solution, but three d
ifferent products in the solid state. The structures of (4) and an unu
sual solid-state photoproduct methyl ydrobenzo[a]cyclopropa[cd]pentale
ne-6b-carboxylate (13) have been determined by X-ray crystal analyses.
