Reductions with hydrosilanes. Reductions with hydrosilanes are methods used for hydrogenation and hydrogenolysis of organic compounds. The approach is a subset of ionic hydrogenation. In this particular method, the substrate is treated with a hydrosilane and auxiliary reagent, often a strong acid, resulting in formal transfer of hydride from ...
Calculus. In integral calculus, integration by reduction formulae is a method relying on recurrence relations. It is used when an expression containing an integer parameter, usually in the form of powers of elementary functions, or products of transcendental functions and polynomials of arbitrary degree, can't be integrated directly.
Swiss Guards ( French: Gardes Suisses; German: Schweizergarde; Italian: Guardie Svizzere) are Swiss soldiers who have served as guards at foreign European courts since the late 15th century. The earliest Swiss Guard unit to be established on a permanent basis was the Hundred Suiss ( Cent-Suisses ), which served at the French court from 1490 to ...
Markó–Lam deoxygenation. The Markó–Lam deoxygenation is an organic chemistry reaction where the hydroxy functional group in an organic compound is replaced by a hydrogen atom to give an alkyl group. [1] [2] The Markó-Lam reaction is a variant of the Bouveault–Blanc reduction [3] and an alternative to the classical Barton–McCombie ...
The bipyridine reagent is produced by reduction of 4,4'-bipyridine in the presence of trimethylsilyl chloride (Me = CH 3): NC 5 H 4 C 5 H 4 N + 2 Li + 2 Me 3 SiCl → Me 3 SiNC 5 H 4 C 5 H 4 NSiMe 3 + 2 LiCl. A typical reduction reaction is the conversion of tungsten hexachloride to the tetrachloride using the silylated pyrazine reagent:
Bouveault–Blanc reduction. The Bouveault–Blanc reduction is a chemical reaction in which an ester is reduced to primary alcohols using absolute ethanol and sodium metal. [1] It was first reported by Louis Bouveault and Gustave Louis Blanc in 1903. [2] [3] [4] Bouveault and Blanc demonstrated the reduction of ethyl oleate and n - butyl ...
