  使用3-氨基-1,2,4-二噻唑-5-硫酮（氢化黄原氢化物）的膦和亚磷酸酯的硫化机理。

  摘要：

  与先前的报告相反，3-氨基-1,2,4-二噻唑-5-硫酮（黄原氢化物）对磷（III）衍生物的硫化不会产生作为额外反应产物的二硫化碳和氰胺。黄原酸氢化物与三苯基膦或亚磷酸三甲酯的反应分别产生三苯基膦硫化物或三甲基硫代磷酸酯，以及已被亲核试剂捕获的硫代氨基甲酰基异硫氰酸酯。该反应途径涉及磷在黄原氢化物的硫代羰基旁边的硫处最初的亲核进攻，然后分解形成产物的intermediate中间体。乙腈中取代的三苯膦和亚磷酸三苯酯硫化的哈米特rho值约为-1.0。活化的熵非常负（-114 +/- 15 J mol-1 K-1），对溶剂的依赖性很小，这与导致过渡态的双分子缔合步骤相一致。ΔS（不等于）和rho值的负值表明，硫化反应的限速步骤是形成具有早期过渡态且几乎没有共价键形成的the离子中间体。亲核攻击的位点也已经通过计算得到证实。ΔS（不等于）和rho值的负值表明，硫化反应的限速步骤是形成具有早期过渡态

  Industrially important triaryl phosphites, traditionally prepared from PCl3, have been synthesized by a diphenyl diselenide-catalyzed one-step procedure involving white phosphorus and phenols, which provides a halogen- and transition metal-free way to these compounds. Subsequent oxidation of triaryl phosphites produces triaryl phosphates and triaryl thiophosphates. Phosphorotrithioates are also prepared

  工业上重要的亚磷酸三芳基酯，传统上由 PCl 3制备，已通过涉及白磷和苯酚的二苯基二硒化物催化一步法合成，这为这些化合物提供了一种不含卤素和过渡金属的方法。随后亚磷酸三芳基酯氧化产生磷酸三芳基酯和硫代磷酸三芳基酯。三硫代磷酸酯也可以由芳香族硫醇和脂肪族硫醇有效地制备。

  The existence of the phosphonium intermediate during sulfurization of triphenyl phosphine with 3-phenyl-1,2,4-dithiazole-5-thione (7a) was proven using kinetic studies. From the Hammett and Brønsted correlations and from other kinetic measurements it was concluded that the transition-state structure is almost apolar for the most reactive 1,2,4-dithiazoles whereas a polar structure resembling a zwitter-ionic

  Six tris(aryloxy)phosphorothionates substituted in the para position of the aromatic rings were synthesized and studied by P-31 NMR, X-ray diffraction techniques and ab initio calculations at a RHF/6-31G** level of theory, in order to find the main structural factors associated with the delta P-31 in these compounds. As the electron-withdrawing (EW) ability of the substituents was increased, an 'abnormal' shielding effect on delta P-31 of the arylphosphorothionates was observed. The analyses of the geometrical properties obtained through both experimental and theoretical methods showed that a propeller-type conformation is preferred for the arylphosphorothionates, except in the case of the tris(O-4-methylphenyl)phosphorothionate, since one of the aromatic rings is not rotated in the same direction as the other two in the solid state. The main features associated with the delta P-31 NMR of compounds 1-6 were a decrease of the averaged O-P-O angle and mainly the shortening of the P=S bond length, which is consistent with an increase of the thiophosphoryl bond order as delta P-31 values go upfield. On the other hand, comparison of the experimental and calculated bond lengths and bond angles involving a bonded atoms to phosphorus of the six compounds suggested that stereoelectronic interactions of the type n(pi)O-sigma*(P=S), n(pi)O-sigma*(P-OAr) and n(pi)S-sigma*(P-OAr) could be present in the arylphosphorothionates 1-6.
