Study of photochemistry without light of substituted benzylidine acenaphthenones

In order to draw a parallel between light induced reactions as well as photochemistry without light (chemiluminescence), the substituted benzylidineacenaphthenones were subjected to dioxetanedione reactions, which are formed in situ by the reaction of 2,4-dimitrophenyloxalate with hydrogen peroxide to provide chrysene derivatives as well as naphthalene 1,8-dicarboxylic acid anhydride and benzoic acid whose structures were determined by IR and 1H NMR spectra.
