Quantitative Synthesis and Formation of Cyclopentapyrene 3,4-Oxide under Simulated Atmospheric Conditions

Article abstract of DOI:10.1021/tx00044a009

Cyclopentapyrene 3,4-oxide (2) has been synthesized in a one-step, quantitative reaction using dimethyldioxirane. The oxide, or its thermal rearrangement products cyclopentapyren-3(4H)-one and cyclopentapyren-4(3H)-one, is formed from cyclopentapyrene (1) under simulated environmental conditions. In one case these products are formed when 1 is adsorbed on model particulates and then exposed to the reaction products of tetramethylethylene and ozone in the gas phase.
