For the first time, we have used activated alumina balls (3-5 mm diameter) for amide synthesis from carboxylic acids (unactivated) and amines (unactivated) under neat reaction conditions that produce no toxic by-products and has the advantages of being low-cost, easily available, heterogeneous, reusable and environmentally benign with no troublesome/hazardous disposal of the catalyst.

(Chemical Equation Presented) Trading places: The metathesis of secondary amides through a transacylation mechanism has been achieved by employing catalytic quantities of an organic imide and a Bronsted base (see scheme). Equilibrium-controlled exchange between various amide pairs is demonstrated for substrates bearing N-alkyl and N-aryl substituents.

Disclosed is a method of manipulating the carboxamide functionality in a catalytic manner. The method includes the steps of reacting amides with or without amines in the presence of various types of metal catalysts, at a temperature of about 250° C. or less.
