The Barton decarboxylation (15) and the Barton modification of the Borodin-Hunsdiecker reaction (16) both exploit the strong propensity of carboxy radicals to decarboxylate and form alkyl radicals. Carboxylation is a chemical reaction in which a carboxylic acid group is produced by treating a substrate with carbon dioxide. Do PhD admission committees prefer prospective professors over practitioners? Rhenium-catalyzed oxyalkylation of alkenes is described, where hypervalent iodine(III) reagents derived from widely occurring aliphatic carboxylic acids were used as, for the first time, not only an oxygenation source but also an alkylation source via decarboxylation. I think that the destabilisation of the cyanide in DMSO and the formation of stable acetonitrile can be considered as the driving force in the second reaction.

For example, benzene can be made by heating soda lime with solid benzoic acid (benzenecarboxylic acid), C 6 H 5 COOH. Decarboxylation of aliphatic carboxylic acid generally requires mild reaction conditions compared to its aromatic counterpart due to the facile extrusion of CO 2 from a less strong C(sp 3)−CO 2 H bond. Was Terry Pratchett inspired by Hal Clement? The solvent choice for DMSO (polar aprotic) is due to low stabilisation of the chloride anion rendering it highly reactive for the nucleophilic attack. パンの耳?

An efficient copper-catalyzed trifluoromethylation of polysubstituted alkenes assisted by decarboxylation of β,γ-unsaturated carboxylic acids has been achieved. There is also an overall increase in entropy due to the formation of gas which drives the reaction forward. In another reaction, arginine dihydrolase catalyzes the conversion of arginine to citrulline, which is further converted to ornithine, finally producing putrescine. The decarboxylation of carboxylic acids to form alkenes has been achieved with lead tetraacetate. 20.11 DECARBOXYLATION OF CARBOXYLIC ACIDS The loss of carbon dioxide from a carboxylic acid is called decarboxylation. The thiamin intermediate is The reductive decarboxylation (e.g., 689 → 690) is carried out in benzene or toluene and the Borodin-Hunsdiecker reaction in a tetrahalomethane. Once the ester has served its purpose in the course of a synthesis, it often becomes necessary to replace the ester group with hydrogen. MathJax reference.
