The Barton reaction, also known as the Barton nitrite ester reaction, is a photochemical reaction that involves the photolysis of an alkyl nitrite to form a δ- nitroso alcohol. Discovered in 1960, the reaction is named for its discoverer, Nobel laureate Sir Derek Barton. [1] Barton's Nobel Prize in Chemistry in 1969 was awarded for his work on ...
Nitrilase was first discovered in the early 1960s for its ability to catalyze the hydration of a nitrile to a carboxylic acid. [2] Although it was known at the time that nitrilase could operate with wide substrate specificity in producing the corresponding acid, later studies reported the first NHase (nitrile hydratase) activity exhibited by nitrilase.
Michael addition reaction. In organic chemistry, the Michael reaction or Michael 1,4 addition is a reaction between a Michael donor (an enolate or other nucleophile) and a Michael acceptor (usually an α,β-unsaturated carbonyl) to produce a Michael adduct by creating a carbon-carbon bond at the acceptor's β-carbon. [1][2] It belongs to the ...
The reduction of nitro compounds are chemical reactions of wide interest in organic chemistry. The conversion can be effected by many reagents. The nitro group was one of the first functional groups to be reduced. Alkyl and aryl nitro compounds behave differently. Most useful is the reduction of aryl nitro compounds.
ritter-reaction. RSC ontology ID. RXNO:0000058. The Ritter reaction is a chemical reaction that transforms a nitrile into an N -alkyl amide using various electrophilic alkylating reagents. The original reaction formed the alkylating agent using an alkene in the presence of a strong acid. [1][2][3][4]
Nucleophilic addition. In organic chemistry, a nucleophilic addition (AN) reaction is an addition reaction where a chemical compound with an electrophilic double or triple bond reacts with a nucleophile, such that the double or triple bond is broken. Nucleophilic additions differ from electrophilic additions in that the former reactions involve ...
The Béchamp reduction (or Béchamp process) is a chemical reaction that converts aromatic nitro compounds to their corresponding anilines using iron as the reductant: [1] 4 C 6 H 5 NO 2 + 9 Fe + 4 H 2 O → 4 C 6 H 5 NH 2 + 3 Fe 3 O 4. This reaction was once a major route to aniline, but catalytic hydrogenation is the preferred method. [2]
Thorpe–Ziegler reaction. The Thorpe–Ziegler reaction (named after Jocelyn Field Thorpe and Karl Ziegler), or Ziegler method, is the intramolecular modification with a dinitrile as a reactant and a cyclic ketone as the final reaction product after acidic hydrolysis. The reaction is conceptually related to the Dieckmann condensation.
