formation:
3˚/4˚ can be created by:

  • SN2 halogenoalkanes using
  • good because primary amines and secondary amines are better nucleophiles than ammonia, therefore multiple substitutions can take place
  • thus not ideal for 1˚

formation:
1˚ can be created by:

  1. SN2 halogenoalkanes using , heating under reflux to form nitrile
  2. reduce to using or with catalyst
