What is the process of making primary amines from nitriles?
Making primary amines from nitriles. The nitrile reacts with the lithium tetrahydridoaluminate in solution in ethoxyethane (diethyl ether, or just "ether") followed by treatment of the product of that reaction with a dilute acid. Overall, the carbon-nitrogen triple bond is reduced to give a primary amine.
What is the process by which an amide can be transformed into an amine?
There are a number of ways in which an amide can be transformed into an amine. Two of these ways have been mentioned already and involve hydrolysis or reduction: As a means of amine synthesis, both methods depend on the availability or the ease of synthesis of the corresponding amide.
What is the most useful amine synthesis strategy?
The reductive amination is the most useful amine synthesis strategy. It affords functionalized amines and doesn’t typically give many unwanted side products. It can also be done single pot making this reaction very useful for the modern synthesis as it allows us to cut the time requirements.
What are the two unique reactions of amines?
The two unique reactions of amines are the Hofmann elimination and the Cope elimination. In the Hofmann elimination, we first perform an overalkylation of an amine. We then use resulting quaternary ammonium salt as a leaving group. An important feature of the Hofmann elimination is that it always gives you the least substituted product.
