Abstract : Bis(trifluoromethyl)iodophosphine sulfide reacts with limited quantities of mercury to give the diphosphorus compound (CF3)2P(S-P(CF3)2 in which the phosphorus atoms are bridged by a sulfur atom. This same compound is better synthesized from the reaction of bis(trifluoromethyl)dithiophosphinic acid with either dimethylaminobis(trifluoromethyl)phosphine or with chlorobis(trifluoromethyl)phosphine

The rotational spectrum of the transient molecule bromo(sulphido)boron, BrBS, has been observed. The molecule was produced by the high-temperature reaction between gaseous dibromo disulphide, Br2S2, and crystalline boron chips at ca. 1000 °C, and was studied by microwave spectroscopy between 26.5 and 40 GHz. The spectrum is that of a linear molecule. Ground-state rotation, distortion and quadrupole coupling constants have been obtained for 10 of the 12 isotopic variants in natural abundance. A wealth of spectroscopic data has been obtained which has allowed an extremely detailed structure analysis to be performed. The resulting bond lengths are rs(BrB)= 1.831(2)Å and rs(BS)= 1.608(2)Å. Transitions due to vibrationally excited states have also been measured and analysed to yield a range of vibration–rotation parameters.
