13 C nuclear magnetic resonance spectra of some halosteroids, 6-ketosteroids, and related compounds
The 13 Cmr spectra of 21-haloprogesterones have been assigned, and chemical shifts compared with those of simple α-haloketones. In addition, the 13 Cmr spectra of some C-5α and C-6β halosteroids are presented, and long range 13 C— 19 F coupling observed between C-19 and the C-6β fluorine in some cas...
