A convenient method for the synthesis of mono- and N,N-disubstituted thioureas by the debenzoylation of N-substituted- and N,N-disubstituted-N′-benzoylthioureas with hydrazine hydrate under solvent-free conditions has been developed. N-Substituted-N′-benzoylthioureas and hydrazine hydrate were mixed, and stirred at room temperature without a solvent to give the corresponding N-substituted thioureas
开发了一种方便的方法,该方法在无溶剂条件下通过水合肼将N-取代的和N,N-二取代的-N'-苯甲酰基硫脲进行苯甲酰化来合成单和N,N-二取代的硫脲。混合N-取代的-N'-苯甲酰基硫脲和水合肼,并在室温下在无溶剂的情况下搅拌,以高收率得到相应的N-取代的硫脲。
