classes of 1,2,4-diazaphosphol derivatives. First, the five-membered heterocyclic P and O anion intermediates acted as nucleophilic agents in the selective construction of C–P and C–O bonds. Second, the phosphinidene served as a phosphorus synthon, allowing for the formation of C–P and C–N bonds. Finally, a stepwise mechanism, supported by DFT calculations, was invoked to explain the reaction selectivity
我们引入基于腙磷烯中间体的可切换化学选择性策略来合成三类 1,2,4-二氮杂磷衍生物。首先,五元杂环P和O阴离子中间体在C-P和C-O键的选择性构建中充当亲核试剂。其次,膦亚基充当磷合成子,允许形成 C-P 和 C-N 键。最后,利用 DFT 计算支持的逐步机制来解释反应选择性。
