What is "organonickel"

a. (context organic chemistry English) Describing any organic compound containing a carbon to nickel bond

Organonickel chemistry is a branch of organometallic chemistry that deals with organic compounds feature nickel- carbon bonds. They are used as a catalyst, as a building block in organic chemistry and in chemical vapor deposition. Organonickel compounds are also short-lived intermediates in organic reactions. The first organonickel compound was nickel tetracarbonyl Ni(CO), reported in 1890 and quickly applied in the Mond process for nickel purification. Organonickel complexes are prominent in numerous industrial processes including carbonylations, hydrocyanation, and the Shell higher olefin process.
