    Abstract: A process for oxidizing a hydroxymethylphosphonic acid compound to produce a formylphosphonic acid compound is described. The oxidation reaction is carried out in the presence of an oxidant and a catalyst. For example, hydroxymethylphosphonic acid (HMPA) is oxidized by oxygen or hydrogen peroxide in the presence of a copper-containing catalyst to give formylphosphonic acid (FPA). Formylphosphonic acid can then be reacted with glycine to produce a condensation product which, upon hydrogenation, yields glyphosate. Glyphosate can be incorporated into various formulations for use as a herbicide. In addition to glycine, formylphosphonic acid can also be reacted with ammonia, ethanolamine, or other primary amines to form a precursor compound, which can be converted to glyphosate.

    Abstract translation: 描述了氧化羟甲基膦酸化合物以产生甲酰膦酸化合物的方法。 氧化反应在氧化剂和催化剂的存在下进行。 例如，羟基甲基膦酸（HMPA）在含铜催化剂存在下被氧或过氧化氢氧化，得到甲酰基膦酸（FPA）。 然后可以将甲基膦酸与甘氨酸反应以产生缩合产物，其在氢化时产生草甘膦。 草甘膦可以并入用作除草剂的各种制剂中。 除了甘氨酸之外，甲酰基膦酸还可以与氨，乙醇胺或其它伯胺反应形成前体化合物，其可以转化成草甘膦。
