Phenylmagnesium

Part of speech: noun

Definitions

1. A chemical compound consisting of a magnesium atom bonded to a phenyl group, commonly used in organic synthesis as a Grignard reagent known for its ability to form carbon-carbon bonds
2. An organomagnesium compound in which magnesium is directly attached to a benzene-derived phenyl ring, frequently employed in creating new carbon frameworks in complex molecules
3. A reagent featuring a magnesium center bound to an aromatic phenyl group, utilized extensively to introduce phenyl groups into various substrates during chemical reactions

Etymology: Phenylmagnesium bromide is the best-known member of this family, and its name is a plain chemical coinage rather than a word with an older life. The stem "phenyl" comes from "phene," the name given in the 1830s to the substance now called benzene, with the "-yl" ending added by chemists to mark a radical, a group of atoms that behaves as a unit within a larger molecule. "Magnesium" was named after Magnesia, a district of Thessaly in Greece, and the element was isolated in 1808 by Humphry Davy. The compound was named in the early twentieth century, after Victor Grignard's discovery in 1900 that magnesium metal reacting with halobenzenes produced reagents that could form new carbon-carbon bonds. Grignard shared the 1912 Nobel Prize in Chemistry for this work, and reagents of this kind are still called Grignard reagents today. The name therefore describes the molecule's parts directly: a phenyl group bonded to a magnesium halide.
