What is "organosilicon"

a. (context chemistry English) Describing any of a series of derivatives of silicon that have at least one alkyl or aryl group, especially one containing at least one carbon–silicon bond. n. Any compound of this kind.

Organosilicon compounds are organic compounds containing carbon– silicon bonds. Organosilicon chemistry is the corresponding science exploring their properties and reactivity. Most organosilicon compounds are similar to the ordinary organic compounds, being colourless, flammable, hydrophobic, and stable. The first organosilicon compound, tetraethylsilane, was discovered by Charles Friedel and James Crafts in 1863 by reaction of tetrachlorosilane with diethylzinc. The carbosilicon silicon carbide is an inorganic compound.
