A novel visible-light-induced hydrodesulfurization of a thioacetal was developed. The reaction operates under mild conditions using user-friendly tris(trimethylsilyl)silane as the reductant and a low catalyst loading of photoactive 4CzIPN. The expansion of the reaction scope was thwarted by the operationally hazardous nature of the process, occasionally producing fire. Careful examination of reaction mixtures allowed to identify silane (SiH₄) as the likely culprit causing the pyrophoricity.

光化学加氢脱硫中的三（三甲基硅烷）硅烷 ─ 方法和热解性


开发了一种新型可见光诱导的硫代缩醛加氢脱硫。该反应在温和的条件下进行，使用用户友好的三（三甲基硅烷）硅烷作为还原剂和光活性 4CzIPN 的低催化剂负载。该过程的操作危险性阻碍了反应范围的扩大，偶尔会产生火灾。仔细检查反应混合物，可以确定硅烷 （SiH₄） 是导致自燃性的可能罪魁祸首。
