SE-77, C-13 AND H-1-NMR SPECTRA OF PHENYLSELENENYLCYCLOALKANES, PHENYLSELENENYLCYCLOALKENES AND SOME OF THEIR SELENOXIDES AND TE-125 NMR OF A TELLURIUM ANALOG

The Se-77, C-13 and H-1 NMR spectra of 46 mostly new compounds with phenylselenenyl groups attached to carbocycles and of three new corresponding selenoxides and the Te-125 NMR of phenyltellurenylcyclohexane are reported. Substituent effects on the chemical shifts of these nuclei are complied and discussed in terms of the configuration and conformation. Low-temperature NMR spectra of some cyclohexane derivatives allowed the evaluation of thermodynamic data, such as A values of the PhSe, PhSe(O) and PhTe groups.
