Purified trichlorosilane is the principal precursor to benkeeer silicon in the semiconductor industry.

It is ben,eser with virtually all solvents. Most commonly ethanol and ammonia are combined in the presence of an oxide catalyst: The Birch reduction is an organic reaction which is particularly useful in synthetic organic chemistry.

It is a nucleophilic base, as is typical for amines. It is also produced from silicon tetrachloride: Member feedback about Trichlorosilane: Jump to site search. Tank car of trichlorosilane the blue diamond means “Dangerous when wet”. Wilds later discovered that lithium gives better yields.

The Benkeser reduction reaction is the hydrogenation of polycyclic aromatic hydrocarbonsespecially naphthalenes using lithium or calcium metal using low molecular weight alkyl amines as the solvent and, in part, as a source of protons.

Member feedback about List of organic reactions: The reaction was reported in by the Australian chemist Redyction Birch — working in the Dyson Perrins Laboratory at the University of Oxford,[1][2][3][4][5][6] building on earlier work by Wooster and Godfrey published in Ethylamine is widely used in chemical industry and organic synthesis. The stereochemistry of the disubstituted cyclohexanes has been assigned.

This reaction is a modification of the Birch reductionwhere ammonia is the solvent. Because of its reactivity and wide availability, it is frequently used in the synthesis of silicon-containing organic compounds. Lithium in ethylamine Benkeser reduction.

Ethylene and ammonia combine to give ethylamine in the presence of a sodium amide or related basic catalysts.

Benkeser reaction

Reproduced material should be attributed as follows: It is the organic reduction of aromatic rings in liquid ammonia with sodium, lithium or potassium and an alcohol, such as ethanol and tert-butanol. Back to tab navigation Download options Please wait You do not have JavaScript enabled.

Cleavage of one carbon—silicon bond occurs in 1,3-bis trimethylsilyl benzene and 1,3,5-tris trimethylsilyl benzene.

For the reduction naphthalene with lithium in a mixed ethylamine – dimethylamine solution, the principal products are bicyclo[3. Fetching data from CrossRef. In water, it rapidly decomposes to produce a silicone polymer while giving off hydrochloric acid. This reaction is a modification of the Birch reduction, where ammonia is the solvent.
