Homework Answers
Solution:
1) Sodium triacetoxyborohydride is a milder and more selective reducing agent towards aldehydes and ketones than sodium borohydride and sodium cyanoborohydride. Therefore, it is more suitable in reductive amination reaction.
2) Excess of benzyl amine and sodium triacetoxyborohydride favours the formation of imine intermediates during the progress of reaction.

Reductive amination is usually a one-pot procedure during which a carbonyl compound is reacted with ammonia or a primary amine to yield an imine. Subsequently the imine is reduced in situ to an amine. The procedure has application in synthesis of biologically active molecules. In this experiment the imine will be prepared quantitatively through a solvent free reaction (green chemistry) between ortho-vanilin and para-toluidine. The imine is...

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...
