  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.

  Transfer of Sulfur from Arsenic and Antimony Sulfides to Phosphorus Sulfides. Rational Syntheses of Several Less-Common P₄S_n Species

  摘要：

  It has been shown that triphenylarsenic sulfide and triphenylantimony sulfide rapidly transfer sulfur to a number of the known phosphorus sulfides. The reactions are performed at or below room temperature in carbon disulfide solutions. The transfers are neither highly selective nor random, making them useful but not ideal for synthetic purposes. The moderate selectivities of the reactions have been used in the assignment of structures to two new phosphorus sulfides, structures with molecular formulas P4S6 and P4S8 The reactions of P4S3 are unusual in that products with 7-9 sulfur atoms in the molecule are formed competitively with low sulfur products. The usefulness of triphenylantimony sulfide is limited by its tendency to undergo reductive elimination of sulfur. This reduction takes the form of a disproportionation to give triphenylantimony and elemental sulfur and has been shown to occur by a second-order process that appears to involve the formation of disulfur, S-2.
