The reaction of sulfur dioxide (SO2) with 1-propanethiol (NPT), 2-propanethiol (IPT), or 2-methyl-2-propanethiol (TBT) catalyzed by boron trifluoride ethrate (BF3OEt2) was investigated. The ratios of dialkyl trisulfide to dialkyl disulfide obtained (RSSSR/RSSR) at an early stage of the reaction were larger than 1 for the reaction of TBT and less than 1 for the reaction of NPT or IPT. The reaction of
研究了二氧化硫 (SO2) 与 1-丙硫醇 (NPT)、2-丙硫醇 (IPT) 或 2-甲基-2-丙硫醇 (TBT) 在三氟化硼乙醚 (BF3OEt2) 催化下的反应。反应初期得到的二烷基三硫化物与二烷基二硫化物的比率(RSSSR/RSSR)对于TBT反应大于1,对于NPT或IPT反应小于1。研究了在硫醇存在或不存在下二硫代亚硫酸盐与 BF3OEt2 的反应。从二硫代亚硫酸盐与 BF3OEt2 反应形成的硫化物组成与 SO2 与硫醇在 BF3OEt2 存在下反应形成的硫化物组成的相似性考虑,二硫代亚硫酸盐作为反应中间体参与反应的可能性讨论了 SO2 与硫醇。
