High Quality Content by WIKIPEDIA articles! A ring whizzer is a fluxional molecule frequently encountered in organometallic chemistry in which rapid rearrangements occur by migrations about unsaturated organic rings.Ring whizzing, also called ring walking, is an intramolecular isomerization that features fluxional process. It results in the change of the relative positions of the substituent groups on a ring. In a typical ring whizzing process, the hapticity of the migrational substituent group doesn`t change.
