Organometallic chemistry

Organometallic Chemistry. Is in charge of the study of the organometallic compounds, are those compounds which possess a chemical bond between an atom of carbon and a metal atom, its synthesis and its reactivity .

Description

In this context, the term “metal” can be defined using an electronegativity scale, assigning the word metal to that element that has a more electropositive character than carbon. From this point of view, elements known as metalloids, such as silicon, are designated as metals .

It can be considered a part of chemistry differentiated from organic chemistry (in which carbon covalently binds to non-metal atoms such as hydrogen , oxygen , nitrogen , phosphorus , sulfur, or halogens ) and also distinct from inorganic chemistry .

Various metallocycles where different transition metals appear attached to cycles of carbon atoms and other atoms or ligands.

Organometallic chemistry is a discipline that encompasses other sub-disciplines of chemistry, such as: organic chemistry, inorganic chemistry, physicochemistry , electrochemistry , to name a few. This transdiscipline of organometallic chemistry makes it possess almost immediate technological applicability in various chemical industries.

To mention just a few cases: catalytic hydrogenation of olefins using homogeneous systems, at lower pressure and temperature, polymerization of ethylene and propylene that generate plastic polymers with a higher degree of tacticity, etc.

History

Its beginning can be established in the mid-19th century with the synthesis of diethylzinc by Edward Frankland in 1849 , mixing ethyl iodide with zinc .

Its true takeoff takes place from 1900 with the development of Grignard reagents, organomagnesium halides. In 1909 Pope and Peachey prepared trimethylplatin iodide , the first alkyl of a transition metal.

In the second half of the 20th century, many industrial processes were developed where knowledge about these compounds was applied, such as the Ziegler-Natta catalysis for the manufacture of polyethylene , a plastic of great interest.
