1,4-Cyclohexanedione
Encyclopedia
1,4-Cyclohexanedione is the 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.
. 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.
Organic compound
An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. For historical reasons discussed below, a few types of carbon-containing compounds such as carbides, carbonates, simple oxides of carbon, and cyanides, as well as the...

Diketone
A diketone is a molecule containing two ketone groups. The simpliest diketone is diacetyl, also known as 2,3-butanedione. Diacetyl, acetylacetone, and hexane-2,5-dione are examples of 1,2-, 1,3-, and 1,4-diketones, respectively...

Preparation
1,4-Cyclohexanedione is prepared in two steps from diesters of succinic acidSuccinic acid
Succinic acid is a dicarboxylic acid. Succinate plays a biochemical role in the citric acid cycle. The name derives from Latin succinum, meaning amber, from which the acid may be obtained....
