The Derivatives of Carboxylic Acids [PDF]

open access: possible, 1986
In the design of new neuromuscular blocking agents, attention is attracted to the derivatives of the esters of various carboxylic and dicarboxylic acids. The reason for this is that they are hydrolyzed in the organism, the duration of their action being, therefore, limited.

Enzyme cascade reactions: synthesis of furandicarboxylic acid (FDCA) and carboxylic acids using oxidases in tandem

, 2015
A one-pot tandem enzyme reaction using galactose oxidase M3–5 and aldehyde oxidase PaoABC was used to convert hydroxymethylfurfural (HMF) to the pure bioplastics precursor FDCA in 74% isolated yield.

Deep eutectic solvents formed between choline chloride and carboxylic acids: versatile alternatives to ionic liquids.

Journal of the American Chemical Society, 2004
Deep Eutectic Solvents (DES) can be formed between a variety of quaternary ammonium salts and carboxylic acids. The physical properties are significantly affected by the structure of the carboxylic acid but the phase behavior of the mixtures can be ...

Synthesis of Carboxylic Acids

1991
From the standpoint of carbonylation chemistry, carboxylic acids and their derived esters, amides, anhydrides, and acyl halides are best regarded as a group of closely related and readily interconvertible compounds based on the formally disconnected structure {[E] +...CO...[Nu]−}. In most cases [E] represents a potentially electrophilic carbon-centered

Carboxylic Acids and Their Derivatives

1978
Radical additions to unsaturated compounds are attractive methods for preparing carboxylic acids and their derivatives (ester, halide, lactone, amide, anhydride). The carboxylic acid function may be in the unsaturated compound, for example cyclopentanone adds to undecylenic acid affording a 70% yield of product [1].

Volatile carboxylic acids

1982
Previous chapters have described the methods required for the extraction and determination of acidic metabolites in physiological fluids. None of the methods described above, except perhaps liquid chromatography of untreated fluid, are suitable for the determination of the short-chain C1–C5 carboxylic acids.

Carboxylic Acids and Phenols

1985
The purpose of this chapter is an inventory of the types of organic acids and phenols in ground water, rain water, interstitial water, river, and lake water. In addition, this chapter discusses the distribution, composition, and chemistry of organic acids and phenols.
