Most the processes of amino-functionalization of CNTs include 3 steps: carboxylation, acyl-chlorination, and amidation. Why don't we directly do the amidation reaction of carboxylated CNTs with amines? Is it because carboxylated CNTs are less reactive, harsh condition, or low conversion?

Dear Huy,
If you do direct reaction of a carboxylated CNT with an amine, your product will be the ammonium salt of the carboxylated CNT and NOT the amide. This is actually a neutralization of the carboxylic acid moiety (an acid) with amine (a base).
-COOH + NH3 gives -COO- NH4+.
Hoping this will be helpful,
Rafik
