1,4-Cyclohexanedione is an organic compound with the formula (CH2)4(CO)2. This white 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. Specifically under basic conditions, the diethyl succinate condenses to give the cyclohexenediol derivative diethylsuccinoylsuccinate. This intermediate can be hydrolysed and decarboxylated to afford the desired dione.10.15227/orgsyn.045.0025 free 1,4-Cyclohexanedione Organic Syntheses Arnold T. Nielsen Wayne R. Carpenter 45 25 1965
This dione condenses with malononitrile to give an intermediate that can be dehydrogenated to tetracyanoquinodimethane (TCNQ).10.1002/14356007.a16_063.pub2 Malonic Acid and Derivatives Ullmann's Encyclopedia of Industrial Chemistry 2007 Strittmatter Harald Hildbrand Stefan Pollak Peter 978-3-527-30673-2
