Abstract

13C nmr chemical shifts and 13C-31P couplings through one, two, and three bonds are reported for eleven carbocyclic phenylaminephosphonates with ring sizes from four to seven. On the basis of these data, inferences regarding preferred conformations are drawn. Low temperature spectra of the 4-methylcyclohexyl derivative show the existence of two conformers, populated in the ratio of approximately 2: 1 at 183 K.
