The Hofmann rearrangement (Hofmann degradation) is the organic reaction of a primary amide to a primary amine with one less carbon atom. [ 1 ] [ 2 ] [ 3 ] The reaction involves oxidation of the nitrogen followed by rearrangement of the carbonyl and nitrogen to give an isocyanate intermediate.
The Hofmann–Martius rearrangement in organic chemistry is a rearrangement reaction converting an N-alkylated aniline to the corresponding ortho and / or para aryl-alkylated aniline. The reaction requires heat, and the catalyst is an acid like hydrochloric acid .
Several United States police forces are known for unique uniform items not commonly used by other departments. Police uniforms in Chicago and Pittsburgh feature peaked hats incorporating the Sillitoe tartan checkerboard design, similar to taxicab decor. The Washington State Patrol and New Mexico State Police wear bow ties.
The least stable alkene (the one with the fewest substituents on the carbons of the double bond), called the Hofmann product, is formed. This tendency, known as the Hofmann alkene synthesis rule , is in contrast to usual elimination reactions, where Zaitsev's rule predicts the formation of the most stable alkene.
In organic chemistry, a rearrangement reaction is a broad class of organic reactions where the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule. [1] Often a substituent moves from one atom to another atom in the same molecule, hence these reactions are usually intramolecular.
Deprotonation of the Seyferth–Gilbert reagent A gives an anion B, which reacts with the ketone to form the oxaphosphetane D. Elimination of dimethylphosphate E gives the vinyl diazo-intermediate Fa and Fb. The generation of nitrogen gas gives a vinyl carbene G, which via a 1,2-migration forms the desired alkyne H.

The Nebraska State Patrol is Nebraska's only statewide full-service law enforcement agency. Serving Nebraska since 1937, State Patrol troopers perform a wide variety of duties. Those include working with communities to improve public safety, enforcing traffic laws and drug laws, investigating crimes, and enforcing the laws and regulations ...
