analogy to most phosphonamides,19 phosphoramides, and 2-0~0-1,3,2-oxazaphosphorinanes unconstrained by small rings.21 These structural insights are valuable for the understanding of bonding in these systems and for the rational design of chiral adjuvants. Further studies on the structure and reactivity of P-stabilized anions are in progress.
是氮的金字塔形吗?O 清楚地将甲基基团置于轴向和赤道位置。我们假设与大多数膦酰胺、19 磷酰胺和不受小环约束的 2-0~0-1,3,2-氧氮杂膦烷类比,2 中的氮更接近三角形。 21 这些结构见解对于理解这些系统和手性佐剂的合理设计。对 P 稳定阴离子的结构和反应性的进一步研究正在进行中。
