Question

1. Submit a detailed mechanism for the synthesis of benzopinacolone starting with benzophenone. 2. Draw the structure for the phenonium ion intermediate. 3. What is the literature value of the melting point of benzopinacol

Answer 1

Answer:

The first stage of this reaction involves the 2-propanol reacting with benzophenone which involves the formation of the most stable carbocation, the reaction is then heated under high temperature and pressure to form benzopinacol, on cooling the benzopinacololone crystallizes out

Melting point of benzopinacolol= 184-186°C

Explanation:

Please find attached the detailed step by step mechanism of synthesis of benzopinacololone
