Technically there are other ketone esters such as acetoacetate bound to D/L 1,3-butanediol (racemic). This diester has been tested more with deep sea divers. It is not commercially available. [10] Another ketone ester is also referred to as a ketone di-ester which is a bond of C6 and R 1,3 butanediol or C8 and R 1,3 butanediol.
Not taking diazomethane in excess results in HCl reacting with the diazoketone to form chloromethyl ketone and N 2. Mild conditions allow this reaction to take place while not affecting complex or reducible groups in the reactant-acid. [3] The reaction requires the presence of a nucleophile . A metal catalyst is required.
The Baeyer–Villiger oxidation is an organic reaction that forms an ester from a ketone or a lactone from a cyclic ketone, using peroxyacids or peroxides as the oxidant. [1] The reaction is named after Adolf von Baeyer and Victor Villiger who first reported the reaction in 1899. [1] Baeyer-Villiger oxidation

To illustrate the mechanism, the Japp-Klingemann ester variation will be considered. The first step is the deprotonation of the β-keto-ester. The nucleophilic addition of the enolate anion 2 to the diazonium salt produces the azo compound 3. Intermediate 3 has been isolated in rare cases.
The Buchner–Curtius–Schlotterbeck reaction is the reaction of aldehydes or ketones with aliphatic diazoalkanes to form homologated ketones. [1] It was first described by Eduard Buchner and Theodor Curtius in 1885 [2] and later by Fritz Schlotterbeck in 1907. [3]
The Kleinspehn synthesis was extended under David Dolphin by the use of unsymmetrical β-diketones (such as 3-alkyl substituted 2,4-hexanediones), which preferentially reacted initially at the less hindered acetyl group and afforded the corresponding 5-methylpyrrole-2-carboxylate esters. N,N-Dialkyl 2-oximinoacetoacetamides also were found to ...
On September 13, 2018, HVMN was the nutrition sponsor for cyclist Vittoria Bussi, who broke the UCI Hour record using HVMN Ketone drinks in the training run up and on the day of the world record. [ 22 ] In the 2019 Tour de France , multiple cycling teams including Team Jumbo–Visma and Lotto–Soudal confirmed use of ketone ester for ...
