reaction with nucleophiles (X = F–, MeO–,H–) gives products with X–P–P+ bonding, hydroxide ion giving the diphosphine monoxide but even this retains partial P–P bonding; the hydride adduct reacts with BunLi to give 1,4-bis(phospholan-1-yl)butane rather than the expected 1,6-diphosphabicyclo[4.4.4]tetradecane.
1,6-二磷双环[4.4.0]癸烷与1,4-双(三氟甲磺酰氧基)丁烷反应制得的1,6-二磷三环[4.4.4.0]十四烷基二三氟甲磺酸盐在酸性水溶液中稳定,并能与亲核试剂反应(X = F –,MeO –,H –)产生具有X–P–P +键的产物,氢氧根离子产生一氧化二膦,但即使这样仍保留了部分P–P键;与卜氢化加合物起反应Ñ栗,得到1,4-双(PHOSPHOLAN -1-基)丁烷而不是预期的1,6- diphosphabicyclo [4.4.4]十四烷。
