OH H+ CH3 H3C OH Esters can be synthesized by an acid-catalyzed nucleophilic acyl substitution between an alcohol and a carboxylic acid; this process is called the Fischer esterification reaction. Because the alcohol oxygen is a poor nucleophile, the carbonyl carbon is made a better electrophile by protonation of the carbonyl oxygen. The steps of the synthesis are all reversible. The reaction is generally driven to completion by using an excess of the liquid alcohol as a solvent, or by...

The Mitsunobu reaction, on the other hand, allows the synthesis of an ester in which the stereochemistry of the alcohol is inverted. The reaction involves a carboxylic acid and an alcohol, as well as triphenylphosphine and an azo compound termed diethyl azodicarboxylate DEAD). As with the Fischer esterification, H20 is formally...

oleh Secondary amines add to aldehydes and ketones to give enamines. Enamines are formed in a reversible, acid-catalyzed process that begins with nucleophilic addition of the secondary amine to the carbonyl group, followed by transfer of the proton to yield a neutral carbinolamine. Protonation of the hydroxyl group converts it into a good leaving group, however there is no hydrogen left on the nitrogen to be lost to form a neutral imine product. Instead, a proton is lost from the...

H3 C H2Br Br2, H30* HC X CH3 HzC CH3 H3C CH3 Aldehydes and ketones can be halogenated at their a-position by reaction with Cl, Br, or 12, under acidic conditions. Using Br2 under acidic conditions, an intermediate enol is formed which adds bromine at the a-position. The reaction stops after the addition of one bromine because the electron-withdrawing halogen decreases the basicity of the carbonyl oxygen, making the protonation less favorable. Not started curved arrows to show the movement...

CH2 1. (CH2CH2hCuli 2. H30* CH3 The coniugate addition of an alkyl group to an ß-unsaturated ketone is one of the more useful 1,4 addition reactions, just as direct additiona more useful 1,2-addition reactions. Conjugate addition occurs via the use of a lithium dialkylcopper reagent, also called a Gilman reagent. The addition of the dialky copper anion to the B-carbon to give a copper-containing intermediate. Transfer of an alkyl group to carbon and release completes the reaction. Draw curved arrows...
