H CH3 1. LDA 2. CHal НН H3C CN H3C CN Monocarbonyl compounds can be alkylated at the a position via the use of lithium disopropylamide, a strong, sterically hindered base Because only one carbonyl group is available to participate in resonance stabilization of the enolate, the a-hydrogens are less acidic than those of P-dicarbonyl compounds and so a stronger base is necessary to completely convert the compound to the enolate. The reaction occurs in a pola aprotic solvent such...

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...

CHz + PhP-CHCH3 - CH3 НАС НАС Aldehydes and ketones are converted into alkenes by means of a direct nucleophilic addition called the Wittig reaction phosphorane, adds to an aldehyde/ketone to give a four-membered cyclic intermediate called an oxaphosphetane. The decomposes to release triphenylphosphine oxide and an alkene. The ylide is formed by reaction of triphenylphosphine, a good nucleophile, with a primary alkyl halide in an Sy2 react base, such as butyllithium. The carbonyl carbon and the carbon originally bonded...
