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.
This is a list of law enforcement agencies in the state of Nebraska.. According to the U.S. Bureau of Justice Statistics' 2008 Census of State and Local Law Enforcement Agencies, the state had 225 law enforcement agencies employing 3,765 sworn officers, about 211 for each 100,000 residents.
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 .
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 ...
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.
A recently initiated investigation into turnover within the Surfside Beach Police Department could become a referendum on its longtime chief. The town council voted 4-3 last week to look into the ...
A video supposedly showing a 'ballot mule' stuffing a ballot box in Nebraska instead recorded a man memorializing his first vote for president.
PIFA can be used to carry out the Hofmann rearrangement under mildly acidic conditions, [11] rather than the strongly basic conditions traditionally used. [ 12 ] [ 13 ] The Hofmann decarbonylation of an N -protected asparagine has been demonstrated with PIDA, providing a route to β-amino- L - alanine derivatives.
