MCQ
In the Gabriel's phthalimide synthesis, phthalimide is treated first with
- ✓${C_2}{H_5}I/KOH$
- BEthanolic $Na$
- CEthanol and ${H_2}S{O_4}$
- DEther and $LiAl{H_4}$
✓
Answer
Correct option: A.
${C_2}{H_5}I/KOH$
a
Gabriel phthalimide is firstly treated with alcoholic Kor fo form potassium phthalimide which on further reaction with ethyl iodide gives Ne ethyl phthalimide, The product $N-$ethyl phthalimite is hydrolysed with dilute $H C$ lo form primary amine, ie. ethylamine. Th is reaction is known as Gabriel phthalimide synthesis.
