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 silicon to carbon.

Triethylsilane is the organosilicon compound with the formula (C 2 H 5) 3 SiH. It is a trialkylsilane. The Si-H bond is reactive. It was first discovered by Albert Ladenburg in 1872 among the products of reduction of tetraethyl orthosilicate with sodium and diethylzinc. [2]
If the potential carbocation can not be stabilized, ether cleavage follows a bimolecular, concerted S N 2 mechanism. In the example, the ether oxygen is reversibly protonated. The halide ion (here bromide) then nucleophilically attacks the sterically less hindered carbon atom, thereby forming methyl bromide and 1-propanol.
Setting aside silane itself, for which is used mainly in the microelectronics industry as a source of Si, hydrosilanes participate in many reactions. Hydrosilanes are mainly used for diverse styles of reduction in both industrial and laboratory-scale reactions. These including deoxygenation, hydrosilylation, and ionic hydrogenation.
The program came about as the result of the Inflation Reduction Act, which included $15 million in funding to study the creation of a website allowing Americans to directly file their taxes to the ...
Two common modes of Lewis acid catalysis in reactions with polar mechanisms. In reactions with polar mechanisms, Lewis acid catalysis often involves binding of the catalyst to Lewis basic heteroatoms and withdrawing electron density, which in turn facilitates heterolytic bond cleavage (in the case of Friedel-Crafts reaction) or directly activates the substrate toward nucleophilic attack (in ...
The hunts described in the study, published Friday in the journal “Frontiers in Marine Science,” occurred between 2018 and 2024 and were captured in images and videos taken by scientists and ...
Canada is set to bring in 395,000 new permanent residents in 2025, 380,000 in 2026 and 365,000 in 2027, down from 485,000 in 2024, in the first multi-year reduction since Ottawa started laying out ...
