|Section2= |Section3= }} Malonic anhydride or oxetane-2,4-dione is an organic compound with chemical formula C3H2O3 or CH2(CO)2O. It can be viewed as the anhydride of malonic acid, or a double ketone of oxetane. Malonic anhydride was first synthesized in 1988 by ozonolysis of diketene.〔 Cotton, F. A.; Wilkinson, G.
