| Abstract: | Deuterium-induced 13C isotope shifts were measured in the 13C {1H} NMR spectra of monodeuteriated cyclododecanones formed upon oxidation of 1-2H1] cyclododecanol with lead tetraacetate. These shifts, when used in conjunction with 13C NMR data of specifically labelled analogues, 2, 2, 12, 12-2H4]- and 2-2H1] cyclododecanone, enabled the ketone formed with lead tetraacetate to be identified as a mixture of 5-2H1]- and 6-2H1] isotopomers. |
