Abstract

The infrared and ultraviolet carbonyl absorptions of 2-bromocyclohexanone have been examined in a variety of solvents. The data are consistent with an equilibrium axial-2-bromocyclohexanone⇄equatorial-2-bromocyclohexanone for which the equilibrium constant varies as a function of solvent over the range 0·3−1·0. The earlier and apparently contradictory data in the literature have been re-examined and are considered to be consistent with this conclusion.

      The individual steps are well described in the literature. Cyclohexanone was reacted with bromine to obtain 2-bromocyclohexanone [21], which was placed in an autoclave with N,N-dimethylamine solution to give 2-N,N-dimethylaminecyclohexanone [22]. Reduction of this ketone with lithium aluminum hydride [23] gave a mixture of cis and trans (25:75) 2-N,N-dimethylaminecyclohexanol, which were subsequently reacted with N,N-dimethylcarbamyl chloride [24] to obtain the cis an trans-2-N,N-dimethylaminocyclohexyl 1-N′,N′-dimethylcarbamate (compounds 1 and 2).

      Using this approach and the MP2-based results, the intermolecular interaction for the equatorial–equatorial dimer is 3.7 kcal mol−1 more attractive than for the most stable axial–axial dimer. This result alone does not guarantee that 2-bromocyclohexanone self-associates; however, Allinger and Allinger [1] determined in the past that the molecular weight of 2-bromocyclohexanone in cyclohexane is 2.7 times larger than the corresponding value for the monomer (176 g mol−1), suggesting self-association. Also, the stronger self-association in the equatorial–equatorial dimer is supported by DFT frequency calculations: while the CO vibration mode oscillates independently for each unit of the axial–axial dimer 8 (1687 cm−1 for unit A and 1691 cm−1 for unit B), the equatorial–equatorial dimer 23 exhibits symmetric and asymmetric CO stretchings (νs = 1698 cm−1 and νa = 1703 cm−1), showing the interrelationship between the units.

      Of course, dipole–dipole stabilization of carbonyl groups is well known. The molecule 2-bromocyclohexanone forms stacked clusters, the size of which depends on the concentration and dielectric constant of the solvent,11 and acetone dimers occur in the vapor phase.12 Allen et al.13 found that 15% of all crystals of compounds that contain carbonyl groups have non-bonded C⋯O distances of less than 3.6 Å between carbonyl groups.
