ChemInform Abstract
The first direct radical pathway from 1-phenylnaphthalene to fluoranthene predominates at lower temperatures. The second pathway involves an arylaryne/anellated cyclopentadienylidenecarbene mechanism. The third pathway involves direct equilibration and is associated with very high activation energies, so that an operation under normal pyrolytic conditions is not probable.
