NMR-spektroskopische Untersuchungen zur Thiolyse von Decachlorocyclopentaphosphazen,N5P5Cl10

NMR Spectroscopic Studies on the Thiolysis Reaction of Decachlorocyclopentaphosphazenen, N₅P₅Cl₁₀ A series of different but exclusively geminally substituted products, N₅P₅Cl_10?n(SR)_n, is formed by reactions of decachlorocyclopentaphosphazene, N₅P₅Cl₁₀, with sodium ethanethiolate, NaSEt, or benzenethiolate, NaSPh, in benzene or ether. The degree of substitution is low (mainly up to n = 4); intensified conditions do not result in further substitution but in decomposition. The compounds were separated by column chromatography and identified by ³¹P NMR spectroscopy. ³¹P chemical shifts and P—P coupling constants of the investigated compounds systematically change with the progressive substitution by SR groups. The chlorine-replacement pattern is discussed.
