Web(160rpm/min). After reaction completed, pH of the mixture was made at 10.0, and the reaction mixture was cooled to -20o, which was then kept in a freeze dryer till all water was removed. The resulted powder was introduced with 1mL water to dissolve and pH of the solution was made at 5.0 with sulphuric acid. The benzilic acid rearrangement is formally the 1,2-rearrangement of 1,2-diketones to form α-hydroxy–carboxylic acids using a base. This reaction receives its name from the reaction of benzil with potassium hydroxide to form benzilic acid. First performed by Justus von Liebig in 1838, it is the first reported example of a rearrangement reaction. It has become a classic reaction in orga…
