A new class of intermolecular olefin aminooxygenation reaction is described. This reaction utilizes the classic halonium intermediate as a regio‐ and stereochemical template to accomplish the selective oxyamination of both activated and unactivated alkenes. Notably, urea chemical feedstock can be directly introduced as the N and O source and a simple iodide salt can be utilized as the catalyst. This
excellent surface catalytic potential of Fe3O4–OSO3H is utilized in the synthesis of symmetrically and unsymmetrically substituted urea derivatives via transamidation reactions. The scope of the surface catalysis is further extended in transamidation reactions of cyclic and acyclic amide derivatives, and in the amidation of fatty acids. In both transamidation and amidation reactions, the catalyst is reusable
摘要 Fe 3 O 4 -OSO 3 H的优异的表面催化潜力可用于通过氨基转移反应合成对称和不对称取代的脲衍生物。在环和无环酰胺衍生物的氨基转移反应以及脂肪酸的酰胺化反应中,表面催化的范围进一步扩大。在氨基转移和酰胺化反应中,该催化剂可重复使用多达五次,而活性没有明显损失。 Fe 3 O 4 -OSO 3 H的优异的表面催化潜力可用于通过氨基转移反应合成对称和不对称取代的脲衍生物。在环和无环酰胺衍生物的氨基转移反应以及脂肪酸的酰胺化反应中,表面催化的范围进一步扩大。在氨基转移和酰胺化反应中,该催化剂可重复使用多达五次,而活性没有明显损失。

Ammonium chloride promotes the selective formation of monosubstituted ureas undermicrowaveirradiation. Most nucleophiles, acid-labile functionalities, and protecting groups are well tolerated in this reaction. By avoiding transition metals and mineral acids, this methodology offers a more sustainable alternative for the synthesis of monosubstituted ureas and their analogs.
