Syntheses of two novel halomethanetriyltrisphosphonic acids are based on an improved preparation of methanetriyltrisphosphonic acid: pKas for their second acidic dissociations show they are âsuperchargedâ relative to pyrophosphoric acid, PPi, while X-ray crystallographic analysis of fluoromethanetriyltrisphosphonic acid establishes its isosteric character relative to PPi.
在改进甲烷三酰三膦酸制备方法的基础上,合成了两种新型卤代甲烷三酰三膦酸:其第二次酸性解离的 pKas 值表明,相对于焦磷酸 PPi,它们具有 "超电荷 "特性,而对氟代甲烷三酰三膦酸的 X 射线晶体学分析则确定了其相对于焦磷酸 PPi 的同位特性。
