The variable-temperature n.m.r. spectra of spirophosphoranes containing a P-phenylseleno group show that in these systems phenylseleno, phenylthio, and phenoxy groups possess similar apicophilicities. In the case of a spirophosphorane containing a benzoxathiaphosphole ring there is no evidence for the presence in solution of an isomer with apical sulphur, i.e. there is here a substantial difference
含有P-苯基硒烯基的螺磷杂环戊烷的可变温度NMR光谱表明,在这些体系中,苯基硒烯基,苯硫基和苯氧基具有类似的亲嗜性。在含有苯并硫杂磷环的螺磷烷中,没有证据表明在溶液中存在具有顶端硫的异构体,即在此处氧和硫之间的亲嗜亲和性存在显着差异,这在苯氧基和苯硫基上并不明显。
