Reactions of Metal π-Complexes
Metal π-complexes are susceptible to a wide range of chemical reagents. However, the three major groups of metal π-complexes—π-olefin, π-cyclopentadienyl, and π-arene metal—demonstrate distinctly characteristic reactions. π-Cyclopentadienyl complexes (metallocenes) exhibit a high degree of aromaticity and undergo many typical aromatic substitution reactions. The π-arene complexes, on the other hand, do not exhibit a discernible degree of aromaticity. This comparative behavior invites diverse speculation on the exact nature of the π-complex bond. The reactions of most π-olefin complexes often parallel those of uncomplexed olefins. Differing behavior is generally explained on the basis of the strength and stability of the metal-olefin bond, which resists attack.
