Organometallic compounds of d-block elements

The transition metals can form complexes since they have vacant d orbitals. They are also termed Coordination compounds. The organometallic compounds of the transition metals could be used as catalysts as well as reagents. For example, organocadmium, organozinc, organocopper, Grignard are used as the reagents for several reactions. Most of the complexes of organo transition metals are used as catalysts for many organic transformation reactions.
