Organometallic have classically been compounds having bonds between one or more metal atoms and one or more carbon atoms of an organyl group. Organometallic compounds are distinguished by the prefix "organo-". The organopalladium compounds are an example of this.
In addition to the traditional metals and semimetals, elements such as boron, silicon, arsenic and selenium are considered to form organometallic compounds, e.g. organomegnesium compounds MeMgI iodo(methyl)magnesium, Et2Mg diethylmagnesium; an organo-lithium compound BuLi butyllithium; an organozinc compound ClZnCH2C(=0)OEt chloro(ethoxycarbonylmethyl)zinc; an organocuprate Li[CuMe2] lithium dimethylcuprate; an organoborane Et3B triethylborane.
The status of compounds in which the canonical anion has a delocalized structure in which the negative charge is shared with an atom more electronegative than carbon, as in enolates, may vary with the nature of anionic moiety, the metal ion, and possibly the medium; in the basense of direct structural evidence for a carbin-metal bond, such compounds are not considered to be organometallic.
Organometallic chemistry is the study of chemical compounds containing bonds between carbon and a metal.
Organometallic chemistry combines aspects of inorganic chemistry and organic chemistry.
This reference is meant for students who are starting out in the area of Organometallic Chemistry as well as those who wish to review and interrelate concepts for their class, Oral Exams or placement tests.
