Phosphate condensation and amination in dilute aqueous solution; reaction of sulphamide with triphosphate and diphosphate
Abstract
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.
