In this experiment, palladium complexes were synthesized from palladium chloride. The initial product was a benzonitrile-palladium complex, but this was reacted with ethylene to form a Cl-bridged ethylene-palladium complex. The structure of this is fascinating for two reasons: first of all, the bridging Cl ligand is interesting, and the way the ethylene bonds to the metal center through its pi-bond is even more interesting. Super cool stuff.
Ferrocene is one of those compounds you just get excited to hear about due to its vast amount of uses and interesting properties. In this lab, ferrocene underwent acid catalysis to add an acetyl group to one of the cyclopentadiene rings. This experiment was initially used to prove the aromatic nature of these Cp rings, but has come to be useful to substitute different things onto ferrocene compounds.
