1-Phenyl-2-pyrrolidinone is a chemical compound that is used in the synthesis of pharmaceuticals and other organic compounds. It is prepared by the Friedel-Crafts reaction between an amide and methyl anthranilate, or by reacting amines with phospotungstic acid. 1-Phenyl-2-pyrrolidinone can be reacted with epoxides to form butyrolactones, which are used in the production of antibiotics such as butyric acid. The reaction mechanism for 1-phenyl-2-pyrrolidinone involves an alpha hydrogen abstraction from a pi bond followed by a beta hydrogen abstraction from another pi bond. This process leads to a free radical intermediate that reacts with oxygen to form phenol, which then undergoes a second oxidation step to form the desired product.
