Comparison among organometallic catalysts, enzyme catalysts, and organocatalysts.

Organometallic catalystEnzyme catalystOrganocatalyst

Wide substrate scope; high catalytic activity; involving tedious process; potential heavy metal pollutionLimited substrate scope; high selectivity and catalytic activity; usually single enantiomerRobust; inexpensive; readily available; nontoxic; inert toward moisture and oxygen; method especially attractive for the preparation of compound that do not tolerate metal contamination (pharmaceutical products)
