Organic Chemistry Amine Reaction

Amine reaction can be tipsssy-topssy but if you can distinguish what is the relationship between amine, amide, carboxylic  and diazonium salt, the reagent would not be hard to recognize since it came out over and over.

For example: Amine ->amide   you have to use carboxylic

If you want to make any substitution to amine to I2 or CN or ring... we must use turn amine to diazonium salt FIRST before substitute the target group.

Most people remember all the reaction how to turn amine to other group but forget that question can ask you how to make an amine from alkyl halide.

See example below... how to make N3 to NH2?

Answer : LiAlH4 /H2O
