Sample of cadmium selenide, a pigment. The parent inorganic selenide is hydrogen selenide (H 2 Se). It is a colorless, malodorous, toxic gas. It dissolves in aqueous solution, to give the hydrogenselenide or biselenide ion HSe −. At higher pH, selenide forms. Solutions of hydrogen selenide and selenide are oxidized by air to give elemental ...
Selenoxide elimination (also called α-selenation) [1] is a method for the chemical synthesis of alkenes from selenoxides. It is most commonly used to synthesize α,β-unsaturated carbonyl compounds from the corresponding saturated analogues. [2] It is mechanistically related to the Cope reaction.
Voltage-gated sodium channels (VGSCs), also known as voltage-dependent sodium channels (VDSCs), are a group of voltage-gated ion channels found in the membrane of excitable cells (e.g., muscle, glial cells, neurons, etc.) with a permeability to the sodium ion Na +. They are the main channels involved in action potential of excitable cells.
[1] [2] [3] Selenium belongs with oxygen and sulfur to the group 16 elements or chalcogens, and similarities in chemistry are to be expected. Organoselenium compounds are found at trace levels in ambient waters, soils and sediments. [4]
Sodium selenide is an inorganic compound of sodium and selenium with the chemical formula Na 2 Se. Preparation. This colourless solid is prepared by the reaction of ...
The Shorigen reaction is also used in the generation of phenylsodium, where an alkyl sodium compound is treated with benzene: [3] RNa + C 6 H 6 → RH + C 6 H 5 Na. The method can also result in the addition of a second sodium. This dimetallation occurs in the meta and para positions. The use of certain alkyl sodium compounds such as n-amyl ...
Sodium hydroselenide is an inorganic compound with the chemical formula Na Se H. It is a salt of hydrogen selenide. It consist of sodium cations Na + and hydroselenide anions − SeH. Each unit consists of one sodium, one selenium, and one hydrogen atom. Sodium hydroselenide is a selenium analog of sodium hydroxide NaOH.
Sodium selenite is the inorganic compound with the formula Na 2 SeO 3. This salt is a colourless solid. The pink coloured pentahydrate Na 2 SeO 3 (H 2 O) 5 is the most common water-soluble selenium compound.
