(1R,2R)-N,N′-Diisobutyl-N,N′-dimethyl­cyclo­hexane-1,2-diamine

The title compound, C(16)H(34)N(2), is a chiral diamine with fixed R configuration at both stereogenic carbon centres of the cyclo­hexane backbone. Due to their different substituents, the two N atoms also become stereogenic. In the crystal structure, the configuration at one of the two nitro­gen centres is fixed, with the free electron pair pointing inward and the isobutyl group in a trans position towards the cyclo­hexane backbone resulting in an R configuration. The isobutyl group at the second N atom, however, is disordered with 75% S configuration and 25% R configuration. In both cases, the isobutyl group is arranged in a trans position towards the cyclo­hexane backbone.
