Synthesis of Benzilic Acid from Benzil. _____ Synthesis of Benzilic Acid from Benzil. When benzil is heated with potassium hydroxide solution, it undergoes a molecular rearrangement to form the potassium salt of benzilic acid, or diphenylglycollic acid. This reaction applies to many 1,2-diketones, and is termed the Benzilic Acid Rearrangement.

The conversion of Benzil to Benzilic acid was first studied by Friedrich Wohler and Justin von Lieberg and is one of the first known rearrangement reactions in organic chemistry. It is a great reaction to introduce students to complex reaction mechanisms. Since Benzil is required to form Benzilic acid, it must first be synthesized from Benzoin.
