Abstract We investigated the mechanism of the reaction of paraformaldehyde with phosphorus trichloride in the presence of carboxylic acids (acetic, propanoic, and formic). Our results revealed that bisphosphonic acids were obtained without the use of water. The structures of the reaction products were studied by 1D and 2D homonuclear and heteronuclear 1H-, 13C-, 31P- NMR spectroscopy. [Supplementary
摘要 我们研究了多聚甲醛与三氯化磷在羧酸(乙酸、丙酸和甲酸)存在下的反应机理。我们的结果表明,双膦酸是在不使用水的情况下获得的。通过1D和2D同核和异核1H-、13C-、31P-NMR光谱研究反应产物的结构。[本文提供补充材料。访问出版商在线版的磷、硫和硅及相关元素,获取以下免费补充文件:附加表格。] 图形摘要
