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 highly efficient and selective.

Paragraph 0041-0043, (2017/05/10)
The invention provides a simple and efficient method for directly preparing an amide compound from an aryl methane derivative and nitrile. In the method, manganese triacetate dihydrate is used as a catalyst, and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone(DDQ) is used as an oxidizing agent. The method has the characteristics that raw materials are cheap and easy to obtain, the source of the nitrile is wide, reaction conditions are mild, the applicability is wide and the like. The method solves the problems that ceric ammonium nitrate (CAN) and a fluorine agent which are used by a method for directly synthesizing amide by using aryl methane and nitrile compounds are hard to treat, atomic economy is poor, the source of the nitrile is narrow and the like.

An efficient and inexpensive synthesis of N-substituted amides 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 and reused four times without any significant loss of its activity.

A number of methods have been proposed for the modification of the Ritter reaction. However, many of these methods involve the use of strongly acidic conditions, stoichiometric amounts of reagents, harsh reaction conditions and extended reaction times. Th
