Organonickel chemistry is a branch of organometallic chemistry that studies the synthesis, properties, and reactivity of organic compounds containing nickel. The study of organonickel chemistry has numerous applications in industries such as petrochemicals, pharmaceuticals, and materials science. Synonyms for organonickel chemistry include nickel organometallics, nickel catalysis, nickel-mediated synthesis, and nickel organic chemistry. Nickel organometallics are a type of organometallic compound that is characterized by a nickel center bonded to one or more organic ligands. They have found applications as catalysts in organic synthesis and as intermediates in the production of various chemicals. Understanding the properties of nickel organometallics is crucial for developing new and efficient synthetic methods in organic chemistry.
