Description
The preparation of ferrocene in a
teaching laboratory setting can be
accomplished by the use of potassium
hydroxide with cyclopentidiene, to form
potassium cyclopentidiene, which is then
reacted with Iron (II) chloride and the
resulting slurry purified by sublimation.
The final product obtained is then
characterized using FTIR and melting
point information.
