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...

It is used to prepare carboxylic acids from primary alkyl halides, lengthening the carbon In progress by two atoms. Thus, the product can be visualized as being a "substituted acetic acid." The reaction consists of three steps: generation of the enolate anion followed by SN 2 reaction with a primary...

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.

МСРВА Alkenes are oxidized to give epoxides on treatment with a peroxyacid, RCo,H, such as metachloroperoxybenzoic acid (MCPBA). Peroxyacids transfer an oxygen atom to the alkene with syn stereochemistry, i.e. both C-O bonds form on the same face of the double bond, through a single step mechanism without intermediates. The oxygen atom farthest from the carbonyl group is the one transferred. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions - XT...
