“…In the brown coal pyrolysis experiments, attack of the fuel by O 2 is not necessary since oxygen is available in the coal itself. Twenty-seven percent of the coal mass is oxygen, of which 25% is phenolic. − Abstraction of the phenolic hydrogen would yield the phenolic type radical shown in Scheme for O 2 attack on the anthryl radical. Formation of indene and its benzologues from phenolic-type ring structures in the coal would then follow via CO elimination.…”

Using high-pressure liquid chromatography with diode-array ultraviolet−visible detection, we have identified benz[f]indene (C13H10) among the pyrolysis products of coal and the model compound anthracene, a three-ring compound representative of the aromatic moieties in coal. The coal pyrolysis experiments are conducted at 700−1000 °C in a fluidized bed reactor; the anthracene experiments, at 900−1000 °C in a laminar flow reactor. This is the first time that benz[f]indene has been identified as a product of either fuel, coal or anthracene. Oxidative ring rupture is proposed as the mechanism responsible for the formation of benz[f]indene and other indene benzologues in these products.
