Reactions of Amines
Mechanism: Required (addition-elimination-deprotonation) Amine must have at least one hydrogen to begin But 1º 2º or NH3 all react well But 3º amines can’t work Some base is required for the deprotonation step and to absorb the HCl For cheap amines excess amine can simply be used
Synthesis and Characterization of Chiral Secondary Amine
Synthesis and characterization of chiral secondary amine catalysts (R)-Ethyl 22'-bis(methoxymethoxy)-11'-binaphthyl-3-carboxylate 11a To a solution of 10(15 g 40 mmol) in THF (600 mL) n-BuLi (24 mL 2 5 M in hexane 60 mmol) was added dropwise at -78 oC under argon atmosphere
Why do tertiary amines react with quaternary ammonium ions?
- Because a tertiary amine is a relatively poor leav- ing group, the reaction requires heat. the leaving group is a tertiary amine CH 3 CH CH 2 HO NCH 3 H 2 O CH 3 CH 3 CH 3 CH 2 CH 2 NCH 3 ++ CH 3 CH 3 + quaternary ammonium ion
What is the formula for ammonium hydroxide and amine synthesis?

NH O CH 3 CH 3 CH 3 + pRoBLem 48 SoL veD Describe a synthesis for the following compound, using the given starting material and any necessary reagents: CH 3 CH 2 CH 2 CH 2 NH 2 CH 3 CH 2 CH CH 2 SoLutioN Although an amine cannot undergo an elimination reaction, a quaternary ammonium hydroxide can.
What is the leaving group of a tertiary amine?
- Because a tertiary amine is a relatively poor leav- ing group, the reaction requires heat. the leaving group is a tertiary amine CH 3 CH CH 2 HO NCH 3
What is the reaction between HOCl and OCL?
- Because HOCl is unstable, it is generated in the reaction mixture by an acid–base reaction between H and OCl (using CH 3 COOH and NaOCl). Secondary alcohols are oxidized to ketones, and primary alcohols are oxidized to aldehydes. OH RR CH secondary alcohol ketone O C R R NaOCl CH 3 COOH 0 C CH 2 OH primary alcohol aldehyde O C R H R NaOCl CH 3
