A simple, mild and synthetically useful method for the desulfurization of cyclic thioureas and related compounds, existing as thiol-thione tautomeric mixtures, by hydrogen peroxide in acetic acid is proposed. The effect of substituting different solvents for the acetic acid was investigated.
提出了一种简单的,温和的,合成上有用的方法,用于在乙酸中通过过氧化氢对环硫脲和相关化合物(以硫醇-硫酮互变异构混合物形式存在)进行脱硫。研究了用不同溶剂代替乙酸的效果。
