in the presence of DTBP and TBAI to afford the transamidated products in good yields. The reactions were conducted underaqueousconditions and good functional group tolerance was achieved. Both aliphatic and aromatic primary amines displayed good activity under metal-free conditions. A radical reaction pathway is proposed.

Acyl hydrazide and acyl hydrazonesynthesis methods were developed. They involve the reaction of an activated amide with hydrazine under transition-metal-catalyst-free conditions. Additionally, acyl hydrazones were synthesized by extending the same reaction procedure in the presence of aldehydes (or ketones). These reactions were performed in an aqueous environment at 25 °C, demonstrating the successful
开发了酰肼和酰腙的合成方法。它们涉及活化酰胺与肼在无过渡金属催化剂的条件下的反应。此外,通过在醛(或酮)存在下扩展相同的反应程序来合成酰基腙。这些反应在 25 °C 的水性环境中进行,证明以高产率成功获得了所需化合物。
