Interest in the metallocenes began in the 1950s when two independent groups (Pauson is often credited as the first) prepared ferrocene by reaction of iron II chloride with cyclopentadienyl magnesium bromide and by reaction of reduced iron with cyclo-pentadiene in the presence of potassium oxide. Ferrocene is a true sandwich compound with the iron resting between two planer and parallel cyclopendadiene groups.
