	Title	N-Methylcarbamoylphosphate, I. Synthese N-Methylcarbamoyl Phosphates, I. Synthesis
	Abstract	Solutions of mono-and bis-N-methylcarbamoyl phosphates in non-aqueous solvents [e.g. acetonitrile, dimethyl formamide, chloroform) and, surprisingly, even in water are readily obtained by the reaction of methyl isocyanate with the solution of an appropriate mono-or dihydrogenphosphate. The course of the reactions and the limited stability of N-methylcarbamoyl phosphate ions in solutions can be monitored through 31 P NMR measurements. Various types of compounds, including a coordination compound of cobalt could.be isolated in crystalline form: [Et3NH]HX, KHX, NH4HX, Na2X • H20, MgX • 4 H20, CaX • H20, SrX • 2 HaO, BaX • H20, ZnX • 5 H20, CdX • 2 H20, [(NH3)5COX]C104, [EtsNHjY, AgY • MeCN, X = MeNHC(0)0P03, Y = [MeNHC(0) 0]2P02.

	Title	Bildung von Amidophosphaten und Amidophosphorsäure aus N-Methylcarbamoylphosphaten Formation of Amidophosphates and Amidophosphoric Acid from N-Methylcarbamoyl Phosphates
	Abstract	The synthesis of various amidophosphates can be readily accomplished in aqueous solutions by the reaction of amines with solutions of sodium, potassium or ammonium N-methylcarbamoyl phosphate, prepared by the reaction of methylisocyanate with the corresponding hydrogen phosphates. Procedures for the synthesis of NH4[03PNH3] and Ca[03PNH2CH3]2 • 4 H20 are described in detail.
