The potentially bidentate fluorophosphine ligand FzPSPFz can be prepared in 75% yield from the reaction of FzPBr and [(CqH9)3Sn]9. On the basis of infrared and Raman spectra, the compound has been assigned a bent conformation of point group Cs or Cz. Nuclear magnetic resonance data confirm the assi

Rate constants for reactions of SiFz radicals have been measured at 2 Torr in a high-temperature fast-flow system. The bimolecular reaction rate constant for SiF\*+F, over a temperature range of 282-617 K can be expressed as (1.0+0.25)X IO-"exp[ -(1850~2OO)lRT] cm3 molecule-' s-', where R is incal m
## Abstract In 2βtrifluoromethylphenyldifluorophosphine the proximate couplings ^4^__J__(^19^F^31^P) and ^5^__J__(^19^F^19^F) are + 68.3 and + 8.3 Hz, respectively. ^1^__J__(^13^C^31^P) is β57.0 Hz, ^2^__J__(^13^Cβ1, ^10^F) is + 9.9 Hz and ^2^__J__(^13^Cβ6, ^13^Cβ6, ^31^P) is + 10.1 Hz. The trifluo
