  2. Bromoethane - Wikipedia

    en.wikipedia.org/wiki/Bromoethane

    Bromoethane is inexpensive and would rarely be prepared in the laboratory. A laboratory synthesis includes reacting ethanol with a mixture of hydrobromic and sulfuric acids. An alternate route involves refluxing ethanol with phosphorus and bromine; phosphorus tribromide is generated in situ. [4]

  3. Bromoform - Wikipedia

    en.wikipedia.org/wiki/Bromoform

    Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.

  4. Hydrogen bromide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_bromide

    Hydrogen bromide prepared by the above methods can be contaminated with Br 2, which can be removed by passing the gas through a solution of phenol at room temperature in tetrachloromethane or other suitable solvent (producing 2,4,6-tribromophenol and generating more HBr in the process) or through copper turnings or copper gauze at high ...

  5. Bromomethane - Wikipedia

    en.wikipedia.org/wiki/Bromomethane

    Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H 3 Br.This colorless, odorless, nonflammable gas is produced both industrially and biologically.

  6. Ethylmagnesium bromide - Wikipedia

    en.wikipedia.org/wiki/Ethylmagnesium_bromide

    Apart from acting as the synthetic equivalent of an ethyl anion synthon for nucleophilic addition, ethylmagnesium bromide may be used as a strong base to deprotonate various substrates such as alkynes: [1]

  7. 1,2-Dibromoethane - Wikipedia

    en.wikipedia.org/wiki/1,2-Dibromoethane

    In organic synthesis, 1,2-dibromoethane is used to brominate carbanions and to activate magnesium for certain Grignard reagents. In the latter process, 1,2-dibromoethane reacts with magnesium, producing ethylene and magnesium bromide , which are innocuous, exposing a more active portion of the magnesium particle to the substrate.

    Jim Harbaugh thinks Jesse Minter could be one-and-done with the Chargers, as the young DC figures to be a hot head coaching candidate in 2025.

  9. Dibromomethane - Wikipedia

    en.wikipedia.org/wiki/Dibromomethane

    Dibromomethane is used as a solvent, gauge fluid, and in organic synthesis (often as 1 H-NMR internal standard). [3] It conviently converts polyols (such as catechols) to their methylenedioxy derivatives, and bromomethylenates enolates. It is a much cheaper precursor to a Simmons-Smith-type reagent than diiodomethane. [5]
