Abstract The photoaddition reaction of acenaphthenequinone and 1,2-naphthoquinone to cycloheptatriene was investigated. In contrast to acyclic α-diketones, various cycloadducts were formed from both quinones; the former giving the (2+2)π-, and (2+6)π-cycloadducts together with the ene-product, and the latter the (2+6)π-, (4+2)π-, and (4+4)π-cycloadducts.
