Reduction benkser aryltrimethylsilanes as a synthetic method. If you are not the author of this article and you wish to reproduce material from it in a third party non-RSC publication you must formally request permission using Copyright Clearance Center. Because of its reactivity and wide availability, it is frequently used in the synthesis of silicon-containing organic compounds. Search articles by author Colin Eaborn. Journal of the Chemical Society, Perkin Transactions 1.
Oh no, there’s been an error
If benmeser material has been adapted instead of reproduced from the original RSC publication “Reproduced from” can be substituted with “Adapted from”. It is a nucleophilic base, as is typical for amines.
Ethylene and ammonia combine to give ethylamine in the presence of a sodium amide or related basic catalysts. For reproduction of material from PCCP: The Benkeser Reduction Reaction. XX is the XXth reference in the list of references.
Benkeser reaction topic The Benkeser reduction reaction is the hydrogenation of polycyclic aromatic hydrocarbons, especially naphthalenes using lithium or calcium metal using low molecular weight alkyl amines as the solvent and, in part, as a source of protons. For reproduction of material from all other RSC journals and books: Back to tab navigation Download options Please wait For reproduction of material from NJC: Member feedback about Birch reduction: This colourless gas has a strong ammonia-like odor.

Lithium in ethylamine Benkeser reduction C. The Benkeser reduction reaction is the hydrogenation of polycyclic aromatic hydrocarbons, benkeseg naphthalenes using lithium rexuction calcium metal using low molecular weight alkyl amines as the solvent and, in part, as a source of protons.
It is a colourless, volatile liquid. Kaiser and Robert A. This reaction is quite unlike catalytic hydrogenation, which usually reduces the aromatic ring all the way to a cyclohexane. The Birch reduction is an organic reaction which is particularly useful in synthetic organic chemistry.
The stereochemistry of the disubstituted cyclohexanes has been assigned.
In water, it rapidly decomposes to produce a silicone polymer while giving off hydrochloric acid. Authors contributing to RSC publications journal articles, books or book chapters do not need to formally request permission to reproduce material contained in this article provided that the correct reducttion is given with the reproduced material.

It is miscible with virtually all solvents. Chlorides Revolvy Brain revolvybrain. Back to tab navigation Fetching data from CrossRef. The major byproducts are silicon tetrachloride chemical formula SiClhexachlorodisilane SiCland dichlorosilane HSiClfrom which trichlorosilane can be separated by distillation. For the reduction naphthalene with lithium in a mixed ethylamine – dimethylamine solution, the principal products are bicyclo[3. Reproduced material should be attributed as follows: This reaction is a modification of the Birch reduction, where ammonia is the solvent.

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. Hydrogen is also produced, as described in the chemical equation: Birch reduction topic Beneser Birch reduction is an organic reaction which is particularly useful in synthetic organic chemistry.
