peri-Diketones with the Ring System of Cyclo-octanaphthalene

peri-Diketones of naphthalene having an eight-membered ring are obtained by oxidative cleavage of cyclopentacenaphthylenes prepared from acenaphthylene-1,2-dione.Cyclo-octanaphthalenes with two peri β-keto ester ketone carbonyl groups exist as mono-enols.The parent 9,10-dihydrocyclo-octanaphthalene-7,11(8H)-dione is a stable though reactive diketone, reduced to a pinacol with exceptional ease and forming stable adducts with water or methanol.
