Silanes / Siloxanes
Silanes are organosilicon or organometallic compounds containing carbon–silicon bonds. A siloxane is a functional group in organosilicon chemistry with the Si−O−Si linkage. Organosilanes have varied uses in organic chemistry from the most frequently employed protecting groups to intermediates in organic synthesis. Silylating agents are mostly used to protect alcohols and phenols but have also found application in the protection of amines, carboxylic acids, amides, thiols, and alkynes. Many organosilicon compounds can undergo coupling reactions (e.g. Hiyama coupling). Allylsilanes are useful intermediates in organic synthesis as the silicon is capable of stabilising both α-anionic charges and β-cationic charges.
