1871Jrnl. Chem. Soc. XXIV. 1161 In the first case, ordinary phosphoryl trichloride is produced: P2O3Cl4 + PCl5 = 3POCl3. 1912J. W. Mellor Mod. Inorg. Chem. xxx. 586 Phosphoryl fluoride, POF3, as well as the other phosphoryl compounds can be made by the action of phosphorus pentoxide, P2O5, on the halogen acid. 1962S. G. Waley in A. Pirie Lens Metabolism Rel. Cataract 360 In the enzymatic reaction, there is a direct transfer of the phosphoryl (O{b2}P{b1}{btr1}OH{bbr1}OH) group from phosphoenolpyruvate to ATP. 1964N. G. Clark Mod. Org. Chem. 553 Phosphoryl chloride (‘phosphorus oxychloride’), POCl3, is a colourless liquid..which reacts slowly with water giving phosphoric acid. 1964W. G. Smith Allergy & Tissue Metabolism viii. 82 Thus the synthesis of glycerophosphatide is dependent on the availability of these phosphoryl bases as well as diglyceride. 1979Science 7 Dec. 1151/1 Figure 7, from this work, represents a hypothetical example in which phosphoryl is conducted from ATP on the left to a substrate S on the right. |
