  • It is stable against CaO, which can be used to remove impurities such as SiF 4 and PF 3.
  • "' Phosphorus trifluorodichloride "'is a chemical compound with the chemical formula PF 3 Cl 2.
  • Volatile crystalline adducts are also formed in combination with BF 3, PF 3, BCl 3, and PCl 3.
  • By reacting iron vapour with B 2 F 4 and PF 3 a substance with the formula ( PF 3 ) FeBF was produced.
  • By reacting iron vapour with B 2 F 4 and PF 3 a substance with the formula ( PF 3 ) FeBF was produced.
  • The phosphine with the strongest ?-acidity is trifluorophosphine ( PF 3 ); its ?-acidity approaches that of the carbonyl ligand.
  • It predicts favorable exothermic formation of PF 4 + F  " from phosphorus trifluoride PF 3 and fluorine F 2 whereas a similar reaction forming PH 4 + H  " is not favorable.
  • In the mixed halide PF 3 Cl 2 the chlorines occupy two of the equatorial positions, Both factors decrease electron density in the bonding region near the central atom so that crowding in the axial position is less important.
  • BF does react with arsine, carbon monoxide, phosphorus trifluoride, phosphine and phosphorus trichloride to make adducts like ( BF 2 ) 3 B " AsH 3, ( BF 2 ) 3 B " CO, ( BF 2 ) 3 B " PF 3, ( BF 2 ) 3 B " PH 3 and ( BF 2 ) 3 B " PCl 3.
