O2H Group Research Associate Interview Questions, Process, and Tips

Q1. N-alkylation of primary and secondary amines
Ans. 
N-alkylation is a process of adding an alkyl group to a primary or secondary amine.
• N-alkylation can be achieved through various methods such as reductive amination, Gabriel synthesis, and Hoffmann degradation.

• Primary amines can be selectively N-alkylated using alkyl halides and a base, while secondary amines require a more reactive alkylating agent such as an epoxide or an alkyl halide.

• N-alkylation is an important reac...read more
