Conclusions
In α-N-morpholylacetone, α-N-piperidylacetone, α-N-dimethylaminocyclohexanone, α-N-piperidylcyclohexanone and α-N-morpholylcyclohexanone in hexane and in benzene the conformational equilibrium about the C-C bond predominantly favors the uneclipsed conformers. For amino derivatives of acetone in chloroform the eclipsed conformer predominates, while for aminocyclohexanones the solvent has no effect on the position of equilibrium. The gauche conformer with respect to the C-N bond predominates in all cases.
