(2-Hydroxyphenylmethylene)bis(phosphine oxides)3 prepared from 2-(diphenylphosphinylmethyl)phenyl phosphinates 2 by oxygen-to-carbon 1,4-phosphinyl migration easily rearrange back into a mixture of 2-(phosphinylmethyl)phenyl phosphinates 2 and 4 under basic conditions or upon heating.
(在碱性条件下或加热时,由 2-(二苯基膦酰甲基)苯基膦酸盐 2 通过氧对碳 1,4-膦酰迁移制备的(2-羟基苯基亚甲基)双(膦氧化物)3 很容易重新排列为 2-(膦酰甲基)苯基膦酸盐 2 和 4 的混合物。
