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...

1. Reductive amination (Carey, Section 22.10) is an important C-N bond forming strategy widely used in the synthesis of biologically active natural product. It's a powerful and reliable strategy that avoids the problem of overalkylation that often accompanies direct alkylation of amines with alkyl halides (Figure 1). secondary amine r tiary amine quemary sa Figure 1: Yields are generally poor as product amines are more nucleophilic and can also react with halide. The result is often a mixture of amines...
