What carbonyl compound and amine are formed by the hydrolysis of each compound?
a.
b.
c.
Short Answer
a.
b.
c.
Step by step solution
Hydrolysis of imines and enamines
Imines and enamines are hydrolyzed to form their corresponding carbonyl compounds in a reversible manner in the presence of an acid.
During the hydrolysis of enamines, the carbonyl carbon comes from the hybridized carbon bonded to the N atom.
Formation of carbonyl compound
Consider the hydrolysis of the given intermediates,
a. The hydrolysis of the given imine would give a molecule of benzaldehyde and cyclopentamine.
b. The hydrolysis of the given enamine would yield a molecule of cyclopentanone and N-methyl benzyl amine.
c. The hydrolysis of this intermediate gives N,N-dimethylamine and 2-methylpropanone.
Products
Hydrolysis of compound a.
The given enamine would give a molecule of cyclopentanone and N-methylbenzyl amine on hydrolysis.
Hydrolysis of compound b.
c. The given enamine would give a molecule of 2-methylpropanal and N,N-dimethylamine on hydrolysis.
