After more than 160 years of oxirane (epoxide) chemistry, the first derivative of a phosphorus analogue, namely oxaphosphirane, has been synthesized. Reactions with borane sulfane, a peroxy compound and elemental sulfur, as well as tetra-chloro--benzoquinone (TOB) reveal a significant destabilization upon increasing the coordination number at phosphorus from σ to σ, thus somehow supporting previous reports on such fleeting species. Theoretical studies provide insight into ring strain energy, ring/ring interconversion and the oxidation pathways.
经过160多年的环氧乙烷（环氧化物）化学研究，首个磷类似物的衍生物——氧杂磷杂环丙烷已被合成出来。与硼烷硫醚、一种过氧化物和单质硫以及四氯苯醌（TOB）的反应表明，随着磷的配位数从σ增加到σ，会出现显著的去稳定化，从而在一定程度上支持了此前关于这类瞬态物种的报道。理论研究为环应变能、环/环相互转化以及氧化途径提供了深入见解。
