โœฆ Synopsis

We have found that "C nmr spectroscopy is a powerful tool for the determination of the structures of &, trans isomers in the phosphorinane family. It is more definitive than 'H nmr spectroscopy; the carbon signals are well separated and have several unique features pointing to the structure, whereas proton signals are generally bunched together and are difficult to interpret. Furthermore, structural effects on chemical shifts are shown to be interpretable on the same grounds now well established for cyclohexane derivatives.
