representative series of alkylthio (or phenylthio)cyclotriphosphazatrienes, N3P3Cl6–n(SR)n, have been prepared and characterised. Very much more pronounced than in alcoholysis or aminolysis, the degree of chlorine replacement in alkanethiolysis is markedly dependent on the reaction conditions. With the alkanethiolates (R = Alk) bis-, tetrakis-, and hexakis-alkylthio-derivatives (n= 2, 4, or 6) are the
借助于链烷硫醇钠(或苯硫醇钠),已制备并表征了一系列代表性的烷硫基(或苯硫基)环三磷氮杂环丁烷N 3 P 3 Cl 6– n(SR)n。比在醇解或氨解中明显得多,烷硫醇解中氯的取代程度明显取决于反应条件。对于链烷硫醇盐(R =烷基),主要的反应产物是双-,四-和六-烷基硫代衍生物(n = 2、4或6)。少量的三烷硫基衍生物(n= 3)也被观察到。用苯硫代硫酸钠(R = Ph),不同取代度之间的反应性差异不太明显,仅获得了双和六烷基衍生物(n = 2或6)。与相应的六烷氧基衍生物N 3 P 3(OAlk)6相比,六烷基硫代环三磷氮杂烯酮N 3 P 3(SAlk)6不能重排为异构的环三磷氮烷。讨论了烷硫基(或苯硫基)磷腈的结构,以及影响氯取代程度的因素以及烷硫基分解(苯硫基分解)的机理。
