“…As mentioned before, the formation of different mixed phosphorus(III) halides have been observed in mixtures of pure P X 3 liquids as well as in other solvents , . Remarkably, no evidence for mixed phosphorus(III) halides was found in our investigations even in cases where the P X 3 species undergo an anion exchange in the ILs.…”

“…As mentioned before, the formation of different mixed phosphorus(III) halides have been observed in mixtures of pure PX 3 liquids as well as in other solvents. [47,[53][54][55][56] Remarkably, no evidence for mixed phosphorus(III) halides was found in our ARTICLE investigations even in cases where the PX 3 species undergo an anion exchange in the ILs. The exchange reactions seem considerably accelerated in the ILs and the equilibrium is shifted completely to the product side.…”

“…First, the formation of a mixed phosphorus(III) halide with the composition PBr 2 Cl or PBrCl 2 might be possible. Both compounds were found by NMR spectroscopy [53,54] and mass [55] spectrometry in liquid mixtures of pure PCl 3 and PBr 3 . Additionally, Dillon et al detected both mixed species in the reaction of PBr 3 with liquid HCl.…”

Mixtures of the phosphorus(III) halides PX3 (X = Cl, Br, I) and the ionic liquids [HMIm][X] (X = Cl, Br, I; HMIm = 1‐hexyl‐3‐methylimidazolium) were studied by nuclear magnetic resonance and Raman spectroscopy. The chloride PCl3 was found to be stable in all mixtures, whereas PBr3 and PI3 can undergo halide exchange depending on the anion of the utilized ionic liquid. The exchange occurs immediately after mixing the compounds at room temperature. In contrast to previous observations made in conventional solvents, intermediate mixed phosphorus halides have not been observed in ionic liquids, indicating a rapid exchange under the applied conditions. Compared to the chemical shifts observed in nuclear magnetic resonance spectra of pure PX3 liquids, the signal of PCl3 is strongly shifted upfield in [HMIm][Cl] indicating strong interaction between the phosphorus halide and the surrounding ionic liquid.

“…A Monsanto group has published extensively on the use of NMR in phosphorus chemistry. They have employed it with particular success in the study of the structural entities in mixed systems (6,44,54,55,132,134,9). NMR has been applied to problems involving triphosphonitrilic halides (68), ClaP=N-P(0)C12 ( 43), cyclic compounds containing the P=0 linkage (83), phosphine sulfides (44), thiopyrophosphate esters (84), and orthophosphite esters and phosphines (103).…”

Previousreviews in this series (121, 122), prepared by Reilly, have been limited to nuclear magnetic resonance, commonly abbreviated to NMR. The present article, following Reilly's lead, is concerned largely with this field but gives some attention to electron spin resonance wdiich is finding application in analytical work to an extent that was not true at the time of the earlier reviews.The articles of Reilly also provide an excellent basic presentation of NMR theory and practice. In this review familiarity with the contents of these two papers or wdth such texts as those of Roberts (125) or Jackman ( 80) is assumed as minimum background. The period from July 1959 to approximately July 1961 is included here.The literature of NMR has expanded very rapidly in the past two years. The writer has a compilation of over 650 references for the period July 1959 through July 1961 and, while he has tried to make it complete, he is certain that many cases, particularly of applications, have been missed. It would be impractical to treat all these references in a review of this kind and, even more to the point, wyould not be desirable.Highly theoretical articles or those wdiich are primarily physical rather than chemical in emphasis are, on the whole,
