Alkali metals have been used to degrade SF in liquid ammonia. The products include metal fluorides. In this study, we reacted K and Ag with SF in a triple quadrupole mass spectrometer. The atomic metal anions were formed by in-source collision-induced dissociation (CID) of their respective oxalate salts as previously described by our group. The only two reaction products observed were SF and SF . At low collision energy, the latter was deduced to be formed via an abstraction by the metal of F from SF formed by electron transfer in the encounter complex between the metal anion and neutral SF. As the collision energy was increased, there was evidence of a CID contribution to SF directly from SF .
碱金属已被用于在液氨中降解六氟化硫（SF）。产物包括金属氟化物。在本研究中，我们在三重四极杆质谱仪中使钾（K）和银（Ag）与六氟化硫反应。如我们小组之前所描述的，原子态金属阴离子是通过其各自草酸盐的源内碰撞诱导解离（CID）形成的。观察到的仅有的两种反应产物是SF 和SF 。在低碰撞能量下，推断后者是通过金属从金属阴离子与中性六氟化硫之间的遭遇复合物中电子转移形成的SF 中夺取氟而形成的。随着碰撞能量增加，有证据表明CID直接从六氟化硫产生了SF 。
