Sulphamide promotes a net intramolecular cyclocondensation of triphosphate to trimetaphosphate in dilute aqueous solution at pH 8–10, as well as the formation of amidophosphates from diphosphate and triphosphate; the relatively saturated character of the reactive S–N bond of sulphamide contrasts that of previously examined aqueous-phase phosphate condensing agents.
在pH 8-10的稀水溶液中,亚磺酰胺促进三磷酸分子内的净分子环缩合成三偏磷酸,以及由二磷酸和三磷酸形成酰胺基磷酸。磺酰胺反应性S-N键的相对饱和特性与先前研究的水相磷酸酯缩合剂形成鲜明对比。
