The reactions between bis(trifluoromethyl)nitroxyl and CF3PX2 (whereX = F, Cl, Br and CN) in 2:1 molar ratio give addition products, [(CF3)2NO]2P(CF3)X2. The bromo and cyano products are unstable. The former decomposes at room temperature to give bromine and perfluoro-2-azapropene, and the latter yields predominantly (CF3)2NOCF3. With CF3PI2, iodine displacement occurs to afford [(CF3)2NO]2PCF3. On

Iodo(trifluoromethyl)phosphine, F3CP(H)I, can be prepared by the reaction of iodine with F3CPH2, or by exchange between F3CPH2 and F3CPl2 with which it is in equilibrium. Chlorine reacts with F3CPH2 to give F3CP(H)Cl, (F3CPH)2, and HCl. Replacement reactions of iodine in F3CP(H)I with silver(I) and mercury(II) halides lead to the preparation of mixtures containing F3CP(H)Cl and of pure F3CP(H)Br. With

Nitricoxide has been found to act as an oxidising agent towards the trifluoromethylphosphino-compounds, CF3PX2(X = F, Cl, H, and CF3), and (CF3)2PX (X = F, Cl, H, and P[CF3]2), reaction occurring in the temperature range 20–100°. The oxidation of (CF3)2PF and (CF3)2P·P(CF3)2 gave the new compounds (CF3)2P(:O)F and (CF3)2P(:O)·O·P(:O)(CF3)2 respectively.

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)

The reaction of P(CF3)nX3–n(L; n= 1 or 2, X = F, Cl, Br, or I) with [Co(CO)3(NO)] at room temperature gives [Co(CO)2(NO)L] as the major product in ail cases except P(CF3)I2. The chloro- and fluoro-phosphines can additionally form [Co(CO)(NO)L2] and the fluorophosphines give intermediates of sufficient thermal stability to allow total substitution of CO under more forcing conditions, giving [Co(NO)L3]
