with mercury and hydrogen iodide the product is (CF3)2PSH, formed by an anti-Arbuzov rearrangement. Bis(trifluoromethyl)dithiophosphinic acid, (CF3)2P(S)SH, is formed by heating sulfur with either (CF3)2PH or (CF3)2PSH. Addition of sulfur to CF3PFNMe2 and PF2NMe2 also gives the corresponding sulfides. The nmr and mass spectra of the new compounds are discussed. (Author)
摘要 : 制备氨基膦硫化物 (CF3)2P(S)NR2,其中 R = H 或 CH3,以及卤代膦硫化物 (CF3)2P(S)X,其中 X = F、Cl、Br 和 I通过用硫加热相应的膦。氯和溴化合物最好通过适当的卤化氢在 (CF3)2P(S)-NMe2 上的作用来制备,而氟化物可以通过三氟化锑对 (CF3)2P(S)Br 的作用而方便地获得。当碘化合物与汞一起摇动时,会形成 (CF3)2PSP(CF3)2,而与汞和碘化氢一起摇动时,产物是 (CF3)2PSH,通过反阿尔布佐夫重排形成。双(三氟甲基)二硫代次膦酸,(CF3)2P(S)SH,是通过将硫与 (CF3)2PH 或 (CF3)2PSH 加热形成的。向 CF3PFNMe2 和 PF2NMe2 中加入硫也会得到相应的硫化物。讨论了新化合物的核磁共振和质谱。(作者)
