Abstract: | Phosphorus(III) Thiohalides: Sd?P? F and S?P? Br. Mass Spectrometric Investigations The compounds S?P? F and S?P? Br are formed by reaction of P(S)FBr2 and P(S)Br3, respectively, with silver at temperatures of about 800 K. S?P? Br is also formed by pyrolysis of P(S)Br3 at temperatures above 298 K. Mass spectrometric equilibrium measurements lead to the heat of formation of S?P? F: ΔH°298(SPFg) = ?260.8 kJ/mol. |
