The conformations and relative configurations of 20 amines, classified according to the following labeling scheme, were analyzed. Series a comprised compounds derived from N-(1-phenylethyl)cyclohexanamine, b comprised derivatives of N-[1-(naphthalen-2-yl)ethyl]cyclohexanamine, c comprised derivatives of N-(diphenylmethyl)cyclohexanamine, and d comprised derivatives of N-(propan-2-yl)cyclohexanamine.

Secondary Amines are prepared in good yields by potential-controlled reduction of aldehydes or ketones at a mercury cathode in an aqueous solution containing a primary amine. For cyclic ketones, high diastereoselectivities are obtained in some cases.
