Heck Reaction: Catalysts, Substrates, and Scope
The Heck reaction, named after the American chemist Richard F. Heck who developed it in the 1960s, is a widely used chemical reaction in organic chemistry. It is a powerful method for forming carbon-carbon (C-C) bonds to create substituted alkenes (olefins) from aryl or vinyl halides and an alkene in the presence of a palladium…
Wittig Reaction: Mechanism and Variations
The Wittig reaction, named after the German chemist Georg Wittig who developed it in the 1950s, is a widely used chemical reaction in organic chemistry. It is a powerful method for synthesizing alkenes (also known as olefins) from carbonyl compounds like aldehydes and ketones.
Hofmann Rearrangement: Understanding its Mechanism and Applications
The Hofmann rearrangement, named after its discoverer August Wilhelm von Hofmann, is a chemical reaction used to convert primary amides into primary amines with one fewer carbon atom.
Beckmann Rearrangement: Mechanisms, Applications, and Innovations
The Beckmann rearrangement is a chemical reaction that involves the conversion of an oxime functional group into an amide functional group. This rearrangement is named after the German chemist Ernst Otto Beckmann, who first described it in the late 19th century.
Curtius Rearrangement: Mechanisms, Variations, and Implications
The Curtius rearrangement, named after the German chemist Theodor Curtius, is a chemical reaction that involves the conversion of a carboxylic acid into an isocyanate compound.
Glyoxylate Cycle: Functions and Significance
The Glyoxylate Cycle is a specialized metabolic pathway found in certain microorganisms, plants, and fungi. It is a variation of the Krebs Cycle (also known as the Citric Acid Cycle or TCA cycle), which is a central component of cellular respiration in most living organisms.
Schiff Base: Synthesis, Properties, and Uses
A Schiff base, also known as an imine, is a chemical compound that contains a functional group composed of a carbon-nitrogen double bond (-C=N-). It is formed when a primary amine (NH2-R) reacts with a carbonyl compound (C=O), typically an aldehyde or a ketone.
Claisen Condensation
The Claisen condensation is a chemical reaction that involves the formation of a new carbon-carbon bond between two ester or ketone molecules in the presence of a strong base, typically an alkoxide ion. This reaction is a fundamental transformation in organic chemistry and is widely used to synthesize beta-keto esters, beta-diketones, and other compounds with…
Dieckmann Condensation
The Dieckmann condensation is a chemical reaction used in organic synthesis to form cyclic compounds, particularly beta-ketoesters or beta-diketones. This reaction is named after its discoverer, the German chemist Walter Dieckmann.
Edman Degradation
Edman Degradation is a widely used chemical method for determining the amino acid sequence in a peptide or protein. This technique was developed by the Swiss chemist Pehr Edman in the 1950s and has since been a fundamental tool in the field of biochemistry.
