Infobox references

1,4-Cyclohexanedione is an organic compound. This tan or yellow crystalline solid is one of the three isomeric cyclohexanediones. This particular diketone is used as a building block in the synthesis of more complex molecules.

Preparation

1,4-Cyclohexanedione is prepared in two steps from diesters of succinic acid. For example under basic conditions, the diethyl ester condenses to give 2,5-dicarbethoxy-1,4-cyclohexanedione. This intermediate can be hydrolysed and decarboxylated to afford the desired dione.^[2]
