含磷五元环五配位化合物的合成

Preparation of Saturated Heterocyclic Compounds with 5-Membered Ring Containing Pentacoordinated Phosphorus

三配位磷化物与烷氧基苯硫醚反应合成了一系列含磷五元环的五配位化合物。在不同温度下,测定了这些化合物的^(19)FNMR。化合物(7)与三氟乙氧基苯硫醚反应生成化合物(19)以及(20)和(21);化合物(11)与六氟异丙氧基苯硫醚反应生成化合物(18)和(21),并对这些反应机理进行了讨论。

The reaction of a variety of saturated heterocyclic compounds with 5-membered ring containning tricoordinated phosphorus with trifluoroethyl benzenesulfenate or hexafluoroisopropyl benzenesulfenate yielded a series of corresponding cyclic phosphoranes.Variable temperature 19FNMR stu dies of these compounds showed no change down to-60℃Reaction of compound(7)with excess trifluoroethyl benzenesul fenate yielded pentakis(trifluoethoxy)phosphorane(19),diphenyl disulfite(20)and compound(21)Compound(11)reacted with hexafluoroisopropyl benzenesulfenate to give compound(18)and(21).The mechanism of these reactions are discussed.
