WebReactions of Aldehydes and Ketones 1. Reversible Addition Reactions A. Hydration and Hemiacetal Formation It has been demonstrated (above) that water adds rapidly to the carbonyl function of aldehydes and ketones. In most cases the resulting hydrate (a geminal-diol) is unstable relative to the reactants and cannot be isolated. WebSeveral amides were obtained in high yields by an efficient method from the corresponding imines which are readily prepared from aldehydes. This procedure involves the oxidation of aldimines with m-CPBA and BF 3 ·OEt 2. In this reaction, the product is strongly influenced by the electron releasing capacity of the aromatic substituent (Ar). G.

WebThe nonreversible esterification reaction proceeds via a nucleophilic substitution reaction. 1. Acting as a nucleophile, the alkoxide ion is attracted to the carbon atom of the carboxyl group. 2. The oxonium loses a proton. 3. An unshared electron pair from the alkoxide ion moves toward the carbonyl carbon, assisting the hydroxyl group's exit.
