TiCl4 proved to be a highly reactive reagent system for the desulfurization of thioamide and thioketone derivatives in excellent yields and short reaction times with high purity. Sulfides were also found to undergo oxidation to sulfones under similar reaction conditions. In most cases, these reactions are highly selective, simple, and clean, affording products in high yields and purity.
H2O2 与 TiCl4 结合被证明是一种用于硫代酰胺和硫酮衍生物脱硫的高反应性试剂体系,收率高,反应时间短,纯度高。还发现硫化物在类似的反应条件下会氧化成砜。在大多数情况下,这些反应具有高度选择性、简单和清洁,可提供高产率和纯度的产品。
