Silyl enol ether

Silyl enol ethers in organic chemistry are a class of organic compounds that share a common functional group composed of an enolate bonded through its oxygen terminus to an organosilicon group.
Silyl enol ethers are important intermediates in organic synthesis.
==Organic synthesis==

* Trimethylsilyl enol ethers can be prepared from ketones in presence of a strong base and trimethylsilyl chloride or a weak base and trimethylsilyl triflate.
* Silyl enol ether can form by capturing any enolate formed in a nucleophilic conjugate addition.〔Organic Syntheses, Coll. Vol. 9, p.564 (1998); Vol. 73, p.123 (1996) (Article )〕〔Organic Syntheses, Coll. Vol. 8, p.277 (1993); Vol. 66, p. 43 (1988) (Article ).〕
* A rather exotic way to generate silyl enol ethers is via the Brook rearrangement of appropriate substrates.
