Ketonic decarboxylation of propanoic acid over a manganese(II) oxide catalyst in a tube furnace affords 3-pentanone. [5] 5-Nonanone, which is potentially of interest as a diesel fuel, can be produced from valeric acid. [6] Stearone is prepared by heating magnesium stearate. [7]
A solution of a carbonyl compound is added to a Grignard reagent. (See gallery) An example of a Grignard reaction (R 2 or R 3 could be hydrogen). The Grignard reaction (French:) is an organometallic chemical reaction in which, according to the classical definition, carbon alkyl, allyl, vinyl, or aryl magnesium halides (Grignard reagent) are added to the carbonyl groups of either an aldehyde or ...
Grignard reagents also react with many "carbonyl-like" compounds and other electrophiles: Reactions of Grignard reagents with various electrophiles. Grignard reagents are nucleophiles in nucleophilic aliphatic substitutions for instance with alkyl halides in a key step in industrial Naproxen production: Naproxen synthesis
The reaction of fatty acids with base is the other main method of saponification. In this case, the reaction involves neutralization of the carboxylic acid. The neutralization method is used to produce industrial soaps such as those derived from magnesium, the transition metals, and aluminium.
Reaction of Weinreb–Nahm amides with Wittig reagents. Additionally, a one-pot magnesium–halogen exchange with subsequent arylation has been developed, showcasing the stability of the Weinreb–Nahm amide and providing an operationally simple method for the synthesis of aryl ketones. [11] One-pot arylation reaction
Calconcarboxylic acid (IUPAC name 3-hydroxy-4-[(2-hydroxy-4-sulfonaphthalen-1-yl)diazenyl]naphthalene-2-carboxylic acid; commonly called Patton and Reeder's Indicator) is an azo dye that is used as an indicator for complexometric titrations of calcium with ethylenediaminetetraacetic acid (EDTA) in the presence of magnesium.

Decarboxylative cross coupling reactions are chemical reactions in which a carboxylic acid is reacted with an organic halide to form a new carbon-carbon bond, concomitant with loss of CO 2. Aryl and alkyl halides participate. Metal catalyst, base, and oxidant are required. Decarboxylative cross-coupling general reaction scheme
Oxidative decarboxylation is a decarboxylation reaction caused by oxidation. Most are accompanied by α- Ketoglutarate α- Decarboxylation caused by dehydrogenation of hydroxyl carboxylic acids such as carbonyl carboxylic malic acid, isocitric acid, etc. [1]
