Question

Can someone explain in words how this mechanism works? I would just like to understand the problems better. Thank you!

for example: I dont understand where the oxygen molecule "disappears" to in the first reaction

1) show how the secondary amine can be I prepared by a successive reductive aminations: ammonium D AHS Dit H /Pd -NH2 Ha/ed ܬܕܢ ܓܓܢܬ

Answer 1

The reaction of aldehydes and ketones with NH₃ or primary amine (R-NH₂) forms imine derivatives. R eto + HAN- R C =N-R +H₂O R=H Ammonia Cimine) R = Alkyl group = Primary amine. + NH₃. (Ammonia) (ketone), Ketone NH THO HINH imine of compound (A) Addition of H₂ across double bond NH Primary amine.

(primary amine) J-160 (Aldehyde) aru con formation) H Addition of H₂ across double bond. Secondary Amine
