将三苯基膦（23.0 mg，0.088 mmol）加入到冷（约 6）干燥苯中的 10.1 mg（0.087 mmol）TMD2（甲基，苯中 1.2 的单线态）中。二氧杂环丁烷在几分钟内完全消耗，以 94% 的产率产生正膦 1。在其核磁共振谱中，甲基区域在苯中显示出 1.0 处的单线态。在冰浴中减压小心除去溶剂，得到白色固体，在室温以上不稳定：nmr
Triphenylphosphine (23.0 mg, 0.088 mmol) was added to 10.1 mg (0.087 mmol) of TMD2 (methyls, singlet at 1.2 in benzene3) in cool (~ 6), dry benzene. The dioxetane was completely consumed within min-utes to yield phosphorane 1 in 94% yield. In its nmr spectrum the methyl region displayed a singlet at 1.0 in benzene. Careful removal of the solvent at reduced pressure, from an ice bath, afforded a white solid, unstable above room temperature: nmr
