The Chugaev elimination is a chemical reaction that involves the elimination of water from alcohols to produce alkenes.The intermediate is a xanthate.It is named for its discoverer, the Russian chemist Lev Aleksandrovich Chugaev (1873–1922), who first reported the reaction sequence in 1899.
Formation of a secondary alcohol via alkene reduction and hydration is shown: The hydroboration-oxidation and oxymercuration-reduction of alkenes are more reliable in organic synthesis. Alkenes react with N-bromosuccinimide and water in halohydrin formation reaction. Amines can be converted to diazonium salts, which are then hydrolyzed.
Sorbitol (/ ˈ s ɔː (r) b ɪ t ɒ l /), less commonly known as glucitol (/ ˈ ɡ l uː s ɪ t ɒ l /), is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the converted aldehyde group (−CHO) to a primary alcohol group (−CH 2 OH).
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
In biochemistry, hydroxylation reactions are often facilitated by enzymes called hydroxylases. These enzymes insert an O atom into a C−H bond. Typical stoichiometries for the hydroxylation of a generic hydrocarbon are these: 2R 3 C−H + O 2 → 2 R 3 C−OH R 3 C−H + O 2 + 2e − + 2H + → R 3 C−OH + H 2 O

Alkenes are precursors to aldehydes (R−CH=O), alcohols (R−OH), polymers, and aromatics. [1] As a problematic reaction, the fouling and inactivation of many catalysts arises via coking, which is the dehydrogenative polymerization of organic substrates. [2] Enzymes that catalyze dehydrogenation are called dehydrogenases.
Swapping out regular candy for these low-sugar or sugar-free candies may help to reduce a person’s caloric intake in the short-term, says Jay. However, these candies have not been shown to aid ...
