13C and 31P NMR chemical shifts and '3C-31P couplings are reported for a series of thirteen l-diethylphosphono-lhydroxycycloalkanes and their alkyl derivatives with carbocyclic ring sizes varying from four to twelve.
## Abstract ^13^C and ^31^P NMR chemical shifts and coupling constants are reported and assigned for the two cyclohexylphenylphosphines, tricyclohexylphosphine and triphenylphosphine. The ^13^C NMR spectra of all compounds except dicyclohexylphenylphosphine could be assigned on the basis of APT exp
## Abstract The easily obtained dimers of phosphole oxides, sulfides and methiodides give ^13^C NMR spectra where carbons within three (sometimes four) bonds of each ^31^P nucleus are doublets of doublets and thus constitute X in an AMX spectrum. Most of the spectra have been completely interpreted
## Abstract The ^13^C NMR spectral data of 18 eudesmane derivatives, mainly acids and esters of natural and synthetic origin, are reported, and the Ξ³βeffect of the epoxide ring in two diastereoisomeric epoxy esters is discussed.
The carbon-13 chemical shifts of mono-and 1,3-disubstituted adamantanes are reported. The effects caused by the substituents are compared with those met in aliphatic and alicyclic compounds. It is shown that the 1,4-interactions have only minor importance in 1-substituted adamantanes. The influence
