Account for the following:
Gabriel phthalimide synthesis is preferred for synthesising primary amines.
Advertisements
उत्तर
Gabriel phthalimide synthesis results in the formation of 1° amine only. 2° or 3° amines are not formed in this synthesis. Thus, a pure 1° amine can be obtained. Therefore, Gabriel phthalimide synthesis is preferred for synthesizing primary amines.
