摘要

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 in high yields.
