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