1,3-dichloro-5,5-dimethylhydantoin (DCH) and 1,3-dibromo-5,5-dimethylhydantoin (DBH) were used as effective oxidizing agents for the oxidation of urazoles and bis-urazoles to their corresponding triazolinediones under mild conditions at room temperature with good to excellent yields.
1,3-二氯-5,5-二甲基酰脲(DCH)和1,3-二溴-5,5-二甲基酰脲(DBH)被用作有效的氧化剂,在温和条件下通过常温氧化脲唑和双脲唑,得到相应的三唑烯二酮,产率良好至优异。
