The Crystal and Molecular Structure of Dodecamethylcyclohexasilane.

Military units and formations of Saskatchewan The Peterson olefination (also called the Peterson reaction) is the chemical reaction of α-silyl carbanions (1 in diagram below) with ketones (or aldehydes) to form a β-hydroxysilane (2) which eliminates to form alkenes (3).

One attractive feature of the Peterson olefination is that it can be used to prepare either cis- or trans-alkenes from the same β-hydroxysilane.

Treatment of the β-hydroxysilane with acid will yield one alkene, while treatment of the same β-hydroxysilane with base will yield the alkene of opposite stereochemistry.

The action of base upon a β-hydroxysilane (1) results in a concerted syn elimination of (2) or (3) to form the desired alkene.

The treatment of the β-hydroxysilane (1) with acid results in protonation and an anti elimination to form the desired alkene.

Potassium tert-butoxide catalyzes the reaction of hydrosilanes and heterocyclic compounds to give the silyl derivatives, with release of H2.

Drogyn informs them that he can save Fred and draw Illyria back to Trimethylsilyl chloride, also known as chlorotrimethylsilane is an organosilicon compound (silyl halide), with the formula (CH3)3SiCl, often abbreviated Me3SiCl or TMSCl.

The principal target of this process is dimethyldichlorosilane, but substantial amounts of the trimethyl and monomethyl products are also obtained.

Moreton-in-Marsh Acylsilanes are a group of chemical compounds sharing a common functional group with the general structure R(CO)-SiR3.

Acylsilanes are starting compounds in the Brook rearrangement with vinyl lithium compounds to silyl enol ethers.

Acylsilanes can be synthesized using the following procedures:.
