Synthesis of 4H-Cyclopentaphenanthrene from Fluorene Skeleton

4-Fluoreneacetic acid was prepared and its chloride was cyclized with AlCl3 to give 4H-cyclopentaphenanthren-8-ol accompanied by the 8,9-dione.These were both reduced to 4H-cyclopentaphenanthrene: the overall yield was 40-50percent from diphenic acid.The phenol was converted to acetoxy and amino substrates.

Flash vacuum pyrolysis of the title diazo compound gives 4H-cyclopentaphenanthrene, which is interpreted as indicating that dibenzocycloheptatrienylidene (13) undergoes the carbene-carbene rearrangement to generate 4-phenanthrylcarbene.The reactivities of 13 are compared with those of other benzoannulated cycloheptatrienylidenes and discussed in terms of the effect of the benzo ring to the activation energy for the rearrangement.

DEGRADATION OF POLYCYCLIC AROMATIC HYDROCARBONS TO RENDER THEM AVAILABLE FOR BIODEGRADATION

A method for the degradation of polycyclic aromatic compounds is disclosed that involves dissolving ozone in a bipolar solvent comprising a non-polar solvent in which is of sufficiently non-polar character to solubilized the polycyclic aromatic compounds, and a polar-water-compatible solvent which is fully miscible with the non-polar solvent to form a single phase with the non-polar solvent. The bipolar solvent with dissolved ozone is contacted with the polycyclic aromatic compounds to solubilize the polycyclic aromatic compounds and react the dissolved polycyclic aromatic compounds with the ozone to degrade the dissolved polycyclic aromatic compounds to oxygenated intermediates. The bipolar solvent is then mixed with sufficient water to form separate non-polar and polar phases, the non-polar phase comprising the non-polar solvent and the polar phase comprising the non-polar solvent and the oxygenated intermediates. The polar phase is then diluted and incubated with bacteria to biodegrade the oxygenated intermediates.
