  Products and Mechanisms in the Oxidation of Phosphorus by Sulfur at Low Temperature

  摘要：

  The oxidation of phosphorus by sulfur at low temperatures (<100 degrees C) has been shown to produce complex mixtures that include 12 of the 17 known binary phosphorus sulfides. Two of these 17 sulfides have been observed in these mixtures for the first time, The rate-determining and first step in the reaction appears to be the formation of the Ss diradical, This proposal is supported by the observed rate at which the sulfides are formed and the distribution of the sulfide product stoichiometries. Photoinitiation of this oxidation at O degrees C produces a similar array of sulfides, The differences in the product distributions between the thermal and photochemical processes facilitate the understanding of the mother-daughter relationships between the products. The effects of oxidation by sulfur and reduction by phosphorus have been determined for several of the known phosphorus sulfides. The characterizations of phosphorus compounds in molten mixtures of phosphorus and sulfur were performed by P-31 NMR and Raman spectroscopy directly on the reaction mixtures.

  Two New Phosphorus Sulfides Jason [1] prepared by the reaction of triphenylantimony sulfide with α-P4S5 and α-P4S7 new phosphorus sulfides. The application of this method on α-P4S4 yielded the main product γ-P4S5 which was assumed to appear in low concentration in phosphorus-sulfur melts by Bjorholm and Jakobsen [2]. In addition the new isomers δ-P4S6 and ϵ-P4S6 were identified by 31P-NMR spectroscopy

  两种新型硫化磷 Jason [1] 由三苯基硫化锑与 α-P4S5 和 α-P4S7 新型硫化磷反应制备。这种方法在 α-P4S4 上的应用产生了主要产物 γ-P4S5，Bjorholm 和 Jakobsen 假设它以低浓度出现在磷硫熔体中 [2]。此外，新的异构体 δ-P4S6 和 ϵ- 通过 31P-NMR 光谱进行鉴定。进一步对α-P4S5和β- 的硫化进行了研究。建议反应路径。在所有情况下，主要反应都是磷的环外加成，然后是插入或进一步加成。
