2,2,3,3-Tetramethylsuccinic acid explained
In chemistry, 2,2,3,3-tetramethylsuccinic acid or 2,2,3,3-tetramethylbutane-1,4-dioic acid is a dicarboxylic acid with the formula, or HOOC-C(CH3)2-C(CH3)2-COOH.[1]
It can be seen as derivative of succinic acid (butane-1,4-dioic acid) with two methyl groups replacing two hydrogen atoms on each of the central carbon atoms of the chain.[2]
Synthesis and chemistry
The compound can also be obtained by thermal decomposition of 2,2,3,3-tetramethyl-4-one-glutaric acid with release of a carbon monoxide molecule.[3]
On heating it forms a heterocyclic anhydride, 3,3,4,4-tetramethyltetrahydrofuran-2,5-dione, with loss of one molecule of water.[4]
