amide synthesis from ester mechanism

How are carboxylic acids converted into amides?
Carboxylic acids are converted into amides in moderate to high yields in the presence of a stoichiometric amount of trimethylaluminium and amines in toluene at 90˚C after 1 hour. S. Chung, D. P. Uccello, H. Choi, J. I. Montgomery, J. Chen, Synlett, 2011, 2072-2074.
What is tertiary amide synthesis?
A general and efficient method enables the synthesis of tertiary amides from readily available tertiary amines and anhydrides in the presence of FeCl 2 as catalyst and tert -butyl hydroperoxide in water (T-Hydro) as oxidant.
How are amides formed?
In an analogous reaction, an amide can be prepared through the reaction of a carboxylic acid and an amine using a coupling agent such as DCC. Simple amides can be prepared by reacting an acid anhydride with an amine. Lastly, amides can be formed through the direct reaction of a carboxylic acid and an amine.
