WebJan 23, 2024 · The fundamental transformation in this reaction is a dimerization of an aldehyde (or ketone) to a beta-hydroxy aldehyde (or ketone) by alpha C–H addition of one reactant molecule to the carbonyl group of a second reactant molecule. Due to the carbanion like nature of enolates they can add to carbonyls in a similar manner as … WebThe chiral alpha-carbon in equation #2 is racemized in the course of this exchange, and a small amount of nitrile is hydrolyzed to the corresponding carboxylic acid. Acyl halides and anhydrides are more easily halogenated than esters and nitriles, probably because of their higher enol concentration.

WebWhen the carbonyl carbon is bonded to one alkyl/aryl group and one OH group, the resulting carbonyl compound can be classified as carboxylic acid and its chemical formula can be generalized to R-COOH. In general, we … WebOct 27, 2024 · In short, the stronger the acid, the smaller the pKa value and strong acids have weak conjugate bases. pKa values describe the point where the acid is 50% dissociated (i.e. deprotonated). Below are tables that include determined pKa values for various acids as determined in water, DMSO and in the gas Phase. dad joke survivors video
