Sift fluorene into a bowl: Manganese oxide octahedral molecular sieves (OMS-2), with the overall composition KMn8O16n H2O, catalyze the mild, green, and efficient oxidation of 9H-fluorene to 9-fluorenone. The involvement of lattice oxygen species has been implicated in a free-radical chain mechanism. In terms of reaction kinetics, the breaking of the C[BOND]H bond is rate controlling.
