Beside hydrolysis of carboxylic acid derivatives in water or water鈥搊rganic solvent mixtures, hydrolases also catalyze the formation of these derivatives in organic solvents. This chapter explains how to plan hydrolase-catalyzed reactions by choosing hydrolases and substrates that are likely to be ...
in the absence of an alcohol nucleophile, stannane10was converted into almost equimolar amounts of formate63andd-glucal64(entries 1 and 2). This reaction is independent from the presence of a Lewis acid additive (for details, see Supplementary Figure1). To investigate the intermediacy of a gl...
The polyol polyester polymers include a reaction product of at least one polyfunctional alcohol, at least one polyfunctional carboxylic acid and at least one monofunctional carboxylic acid, wherein the polyfunctional alcohol includes about two to about ten carbon atoms, the polyfunctional carboxylic acid...
Carboxylic acids and esters decompose to give alkenes and CO above 200 °C in the presence of palladium catalysts.183 Acid anhydrides were decarbonylated with various catalysts, the nature of the reaction products depending strongly on the nature of the metal. Octacarbonyldicobalt partially decarbon...
Carbon dioxide is formed in this reaction which is what causes the bubbling that will be seen. A carboxylic acid is a functional group where the carbon is connected to an alcohol and double bonded to an oxygen. Since there are two oxygen atoms connected to the carbon if the hydrogen is ...
Oxidative activities of unmodified and HAc-modified MnO x . a Mass-specific activity (mmol gcat-1 h-1) of MnO x in benzyl alcohol oxidation as a function of the organic acid/MnO x ratio. b Mass-specific activity (mmol gcat-1 h-1) of MnO x in benzyl alcohol ammoxidation as...
Disclosed are methods for synthesizing an ester or a carboxylic acid from an organic alcohol. To form the ester one reacts, in the presence of oxygen gas, the alcohol with methanol

Severely sterically hindered secondary aminoether alcohols are prepared by reacting an organic carboxylic acid or alkali metal salt of an organic carboxylic acid with a sulfonyl halide, a sulfuryl halide, a mixed sulfuryl ester halide or a mixed sulfuryl amide halide to yield a sulfonic-carboxylic ...
More particularly, the use of an aromatic carboxylic acid in an asymmetric catalysis reaction with, as catalysts, chiral monosulphonylated and carbonylated derivatives of a diamine or an aminoalcohol, with a pyrrolidinyl group. The invention particularly relates to asymmetric aldolisation and keto...
