to find new pathways to bis(phosphonate) structures we report on their synthesis from tris(trimethylsilyl) phosphite and acid anhydride. This new synthesis allows a direct access to a 1-hydroxymethylene-1,1-bis(phosphonic acid) functionalised by a carboxylic function on the side chain. Moreover, we describe the formation of an original cyclic bis(phosphonate) obtained from phthalic anhydride. (© Wiley-VCH
在继续我们寻找双(膦酸酯)结构的新途径的工作中,我们报告了它们从三(三甲基甲硅烷基)亚磷酸酯和酸酐的合成。这种新的合成允许直接获得由侧链上的羧基官能化的 1-羟基亚甲基-1,1-双(膦酸)。此外,我们描述了从邻苯二甲酸酐获得的原始环状双(膦酸酯)的形成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
