The 77Se, 13C and 1H NMR spectra of 46 mostly new compounds with phenylselenenyl groups attached to carbocycles and of three new corresponding selenoxides and the 125Te NMR of phenyltellurenylcyclohexane are reported. Substituent effects on the chemical shifts of these nuclei are compiled 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.
报道了46个主要为新化合物(具有连接到碳环上的苯基亚硒基团)以及三个新的相应亚硒氧化物的77Se、13C和1H NMR光谱,以及苯基碲基环己烷的125Te NMR光谱。根据构型和构象,对这些核的化学位移的取代基效应进行了汇编和讨论。一些环己烷衍生物的低温NMR光谱使得能够评估热力学数据,例如PhSe、PhSe(O)和PhTe基团的A值。
