Can 3O amines be alkylated to form quaternary 4O ammonium salts?
Even 3º-amines may be alkylated to form quaternary (4º) ammonium salts. When tetraalkyl ammonium salts are desired, as shown in the following example, Hünig's base (N,N-diisopropylethylamine) may be used to scavenge the HI produced in the three S N 2 reactions. Steric hindrance prevents this 3º-amine (Hünig's base) from being methylated.
How amines are soluble in water?
For amines one can take advantage of their basicity by forming the protonated salt (RNH 2+ Cl − ), which is soluble in water. The salt will extract into the aqueous phase leaving behind neutral compounds in the non-aqueous phase. The aqueous layer is then treated with a base (NaOH) to regenerate the amine and NaCl.
Is amine salt polar or polar?
As a result, the amine salt functional group is highly polar, with a positive charge on the nitrogen that is balanced by the negative charge from the anion of the acid. In the case of hydrochloric acid, this is the chloride ion, Cl –. Recall that, in a classical acid-base reaction, one of the products is called a salt (5).
