efficient and inexpensive synthesis of N-substitutedamides from the reaction of aliphatic and aromatic nitriles with various benzylic alcohols (secondary and tertiary) and tert-butyl alcohol by refluxing nitromethane via the Ritter reaction catalyzed by aluminum hydrogen sulfate [Al(HSO4)3] is described. The catalyst which is an air-stable, cost-effective solid acid could be readily recycled by filtration

Preparation of different amides via Ritter reaction from alcohols and nitriles in the presence of silica-bonded N- propyl sulphamic acid (SBNPSA) under solvent-free conditions
of methods have been proposed for the modification of the Ritterreaction. However, many of these methods involve the use of strongly acidic conditions, stoichiometric amounts of reagents, harsh reactionconditions and extended reaction times. Therefore, the development of mild, efficient, convenient and benign reagents for the Ritterreaction is desirable. In this research, we have developed a clean
