This thesis mainly introduced that ureas and semicarbazides were synthesized by oxidation of corresponding thioureas and thiosemicarbazides using 30% peroxide as oxidant.

本文主要介绍了以30%双氧水作为氧化剂氧化硫脲、氨基硫脲来备相应脲和氨基脲类化合物。

A new convenient and general one-step route for preparing azines by treating aromtic aldehydes and semicarbazide with anhydrous zinc chloride as catalyst is described.

吖嗪是用泛化合物,如作染料,光敏物质,聚合单体,另外它们还是加成反应母体化合物。
