Although 1,2σλ-oxaphosphetanes have been known for a long time, the "low-coordinate" 1,2σλ-oxaphosphetanes have only been known since their first synthesis in 2018 via decomplexation. Apart from ligation of this P-heterocycle to gold(I)chloride and the oxidation using -chloranil, nothing on their chemistry has been reported so far. Herein, we describe the synthesis of new 1,2σλ-oxaphosphetane complexes (-) and free derivatives (-), as well as reactions of with chalcogens and/or chalcogen transfer reagents, which yielded the -chalcogenides (-; Ch = O, S, Se). We also report on the theoretical results of the reaction pathways of -phenyl-substituted 1,2 σλ-oxaphosphetanes and ring strain energies of 1,2σλ-oxaphosphetane -chalcogenides.
虽然 1,2σλ-氧杂膦环已烷早已为人所知，但直到 2018 年通过去络合作用首次合成“低配位”1,2σλ-氧杂膦环已烷后，人们才对其有所了解。除了这种磷杂环与氯化金的键合以及使用 -氯代醌的氧化之外，目前尚未报道其化学性质。在此，我们描述了新型 1,2σλ-氧杂膦环已烷配合物 (-) 和游离衍生物 (-) 的合成，以及与硫属元素和/或硫属元素转移试剂的反应，这些反应生成了 -硫属化物 (-; Ch = O, S, Se)。我们还报告了 -取代苯基 1,2 σλ-氧杂膦环已烷的反应途径的理论结果和 1,2σλ-氧杂膦环已烷 -硫属化物的环张力能。
