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
Mn-Catalyzed oxidative amination of benzylic C(sp3)–H bonds with nitriles is disclosed, which enables the synthesis of a broad range of secondary amides in moderate to excellent yields under mild conditions. The interaction between Mn(III) and DDQ facilitates the oxidation and makes it highlyefficient and selective.
