Abstract

A carbon-13 NMR spectroscopic study of α-aminonitriles derived from piperidines has been conducted. The substituent effects for cyano group in the nitrogen heterocycles is shown to obey strict regularities. The preferred conformation of a lone cyano group located to the nitrogen is found to be equatorial.
