%X Flash vacuum pyrolysis of 5-(4&#8242;,7&#8242;-dimethyl-1&#8242;,3&#8242;-dihydro-1&#8242;,3&#8242;-ethano-2&#8242; H-inden-2&#8242;-ylidene)-2,2-dimethyl-1,3-dioxan-4,6-dione (13) at temperatures in the range 600-750&#176;p led to complex mixtures, but at higher temperatures (850&#176;) it was converted into 3-methylacenaphthylene (major) and 1,4-dimethylnaphthalene (minor). 5-Ethenyl-1,4-dimethylnaphthalene on f.v.p. at 850&#176; gave 5-methylacenaphthylene together with other compounds and was not on the reaction pathway.
