purity, from the corresponding tetraalkylammonium dithionites (prepared by a modification of the known [NEt4]2[O2SSO2](s) preparation). While the [NEt4]+ salt is stable at rt; the [NMe4]+ salt has only limited stability at −78 °C. Vibrational spectra assignments for the anion in these salts were distinctly different from those for the anion in salts containing the long-known [O3SSSO3]2– dianion, the most
一摩尔当量的气态SO 2被紫色TDAE [O 2 SSO 2 ](s)吸收,产生红色的,基本上是光谱纯净的TDAE [O 2 SS(O)2 SO 2 ](s);在长时间撤离的情况下,该产品损失SO 2(g),从而再生TDAE [O 2 SSO 2 ](s)。类似地,可以从相应的四烷基二硫代亚硫酸氢盐中制备[NR 4 ] 2 [O 2 SS(O)2 SO 2 ](s)(R = Et,Me)(尽管纯度较低) [NEt 4 ] 2 [O2 SSO 2 ]的准备)。[NEt 4 ] +盐在rt时稳定;[NMe 4 ] +盐仅在-78°C下具有有限的稳定性。这些盐中阴离子的振动光谱分配与包含众所周知的[O 3 SSSO 3 ] 2–二价阴离子(最热力学稳定的[S 3 O 6 ] 2– ]盐的阴离子的振动光谱分配明显不同)(我们制备的TDAE [O 3 SSSO 3 ]·H 2O(s),并通过X射线衍射和振动分析获得其结构)。使用具有[O
