Organometallic science is the study of chemical compounds containing at least one metal-carbon bonds Many of these early compounds were prepared specifically from the metal by oxidative addition of alkyl halides. Every one of these metals have reasonably negative reduction potentials. Organometallic Compounds have been utilized as a part of medication for quite a long time, yet with little endeavour to plan the compound to be utilized and with small comprehension of the sub-atomic premise of their instrument of activity. Cisplatin is an anticancer medication which is just utilized as chemotherapy specialist, assumed significant part in building up the field of therapeutic inorganic science. Organometallic compounds of Li, Mg (Grignard reagents) are among probably the most essential natural reagents. Uses of Organometallic compounds are increased because of excess used of these compounds in medicine world.
