Question

Will a reductive amination reaction occur between N, N-dimethybenzylamine and benzaldehyde? Please explain your reasoning. If you take which the melting point of the both crude salt and the recrystallized salt one do you expect to be higher and why? Why is the NaBH_4 is not added at the beginning of the reaction with the carbonyl compound and the amine? What is "Green Chemistry"? Describe which principle of "Green Chemistry" does a solvent free reaction address? You may do some research to answer this question: please write down any references used. Show two ways that you can synthesize the following compound using a reductive amination reaction.

Explanation / Answer

(1) No,

Becuase N.N-dimethylbenzylamine does not have any hydrogen atoms attached to Nitrogen. SO, no active reaction occured between N,N-dimethylbenzylamine and benzaldehyde.

C6H5- CH2 - N(CH3)2 - No hydrogens on N

(2) Recrystellised salt has higher melting point than crude salt. Becuase recystallised salt is a pure one where as crude salt is impure.
According to one of the colligative properties i.e. depreesion freezing point, presence of impurities can lower the freezing point (or melting point)
