Summary

  1. 1.

    2,2′-Methylenedi-1,3-cyclohexanedione and 2,2′-methylenebisdimedon readily form diesters and diethers under the action of acylating agents and of diazomethane.

     
  2. 2.

    When treated with dilute potassium hydroxide solution, 2,2′-methylenedi-l,3-cyclohexanedione readily undergoes selective hydrolytic cleavage with formation of 7-(2,6-dioxocyclohexyl)-5-oxoheptanoic acid (XII).

     
  3. 3.

    On treatment with bromine in a mixture of chloroform and water, 2,2′-methylenebisdimedon is converted into the tricyclic triketone (XVII).
