ChemInform Abstract: Vinyl Ethers with Epoxy Groups. Part 18. Reactions with Carboxylic Acidsoxirane derivativesIn the presence of catalytic amounts of perfluorobutyric acid the reaction between the vinyloxyepoxy derivative (I) and the aliphatic and aromatic acids (II) proceeds regiospecifically at the...
The reaction of vinyl acetate with carboxylic acids in the presence of sulfuric acid catalyst gives a mixture of the acylals ethylidene diacetate, 1-acetoxy-1-acyloxyethane, and 1,1-diacyloxyethane. By contrast, the homologous isopropenyl acetate gives the ester-acid interchange reaction as well ...
Herein, triazenyl alkynes were disclosed as versatile building blocks in a multicomponent reaction with carboxylic acids, aldehydes and anilines to furnish β゛mino amides with the achievement of high diastereoselectivity and structural diversity. In this process, triazenyl alkynes were bifunctional that ...
Recent developments in decarboxylative cross-coupling reactions between carboxylic acids and N–H compounds. RSC Adv. 2019, 9, 8964–8976. [Google Scholar] [CrossRef] [PubMed] Cheng, L.-J.; Mankad, N.P. C–C and C–X coupling reactions of unactivated alkyl electrophiles using copper ...
Kinetic and product studies of Criegee intermediate reactions with halogenated and non-halogenated carboxylic acids and their implications in the troposphere Criegee intermediates are important species formed during the ozonolysis of alkenes. Direct measurement and modelling studies have shown that reactions of...
Ytterbium triflate catalysed FriedelâCrafts reaction using carboxylic acids as acylating reagents under solvent-free conditions The FriedelCrafts acylation of 1-naphthol and phenol derivatives with carboxylic acids were investigated by using a catalytic amount of metal-triflate, in ... W Su,...
I begin by comparing their mechanism to a man getting hit in the groin with a football. I then teach specific reaction examples, which include reactions of acyl (acid) chlorides, acid anhydrides, esters, carboxylic acids, and amides. --Dr. Mike Christiansen from Utah State University...
though that reaction with fluorine is not possible. Halogenation of the α–hydrogen in carboxylic acids with bromine or chlorine can occur via the Zell-Volhard-Zelinsky reaction, however a catalyst such as P or PBr3 is necessary. The easier it is to enolize a substrate, the easier it is ...

Pyridine-2-carboxylic acid, pyridine-2,3-dicarboxylic acid, and pyridine-2,4-dicarboxylic acid or their [(Ph3P)2N]+ salts react with the triply bonded dirhenium(II) complex Re2Cl4(μ-dppm)2 (dppm = Ph2PCH2PPh2) in refluxing ethanol to afford unsymmetrical substitution products of the type...
