What is 1 2 diaminocyclohexane?

1,2-Diaminocyclohexane

1,2-Diaminocyclohexane, also known as 1,2-cyclohexanediamine (DACH), is an organic compound with the formula C6H10(NH2)2. It exists as cis and trans isomers.

Key Properties & Information:

  • Isomerism: The compound exists as cis and trans isomers. The trans isomer is chiral, existing as two enantiomers, (1R,2R)- and (1S,2S)-1,2-diaminocyclohexane. The cis isomer is achiral (not chiral). Understanding the differences in these isomers is crucial in applications. More information about isomerism can be found.

  • Synthesis: It can be synthesized through various routes, including the hydrogenation of 1,2-diaminobenzene (phenylenediamine). The relative ratios of cis and trans isomers can be controlled through catalyst choice and reaction conditions. More information about synthesis can be found.

  • Chirality: The trans-1,2-diaminocyclohexane exists as a pair of enantiomers. These enantiomers are important in asymmetric catalysis and chiral resolution. More information about chirality can be found.
