摘要：

Photooxygenation of acenaphthylene (AN) sensitized by cyano-anthracenes was carried out in acetonitrile. The reaction leads to the initially-formed three precursors including acenaphthenone (ANO), acenaphthenequinone (AQ) and cis-dimer of AN (c-DAN). Each precursor undergoes a distinct sequential photooxygenation process, affording a series of carbonyl-containing products. The studies including product distribution, solvent-dependence, enhancement effect of biphenyl and fluorescence quenching etc. indicate that the title reactions proceed via a parallel three-sequence process in which the main pathways involve electron transfer mechanism.
