A highly effective Co(II)-based system has been developed for catalytic intramolecular C−H amination with phosphoryl azides without the need of terminal oxidant or other additives, resulting in the high-yielding production of cyclophosphoramidates with nitrogen gas as the byproduct. Additional features of this new catalytic system include the amination of primary C−H bonds and formation of 7-membered-ring
已开发出一种高效的基于Co(II)的系统,用于用磷酰叠氮化物催化分子内CH氨基化反应,而无需末端氧化剂或其他添加剂,从而以氮气为副产物高产环磷酰胺酯。这种新的催化体系的其他特征包括一级CH键的胺化和7元环结构的形成。
