diethoxyphosphonate group comprises an effective agent to achieve negative charge migration in TypeIIAnionRelayChemistry (ARC). The process involves a [1,4]-phosphorus-Brook rearrangement that proceeds via a phosphacyclic intermediate leading to an anion that can be captured by reactive electrophiles. In the absence of an exogenous electrophile, the anion derived via phosphorus migration undergoes
二乙氧基膦酸酯基团是在 II 型阴离子继电器化学 (ARC) 中实现负电荷迁移的有效试剂。该过程涉及 [1,4]-磷-布鲁克重排,该重排通过磷环中间体进行,导致阴离子可以被反应性亲电试剂捕获。在没有外源亲电试剂的情况下,通过磷迁移产生的阴离子经历膦酸酯基团的内部置换,产生环丙烷的非对映异构混合物。
