| Chemistry of Poly functional Molecules, 75 [1] The Reaction of 5-Bromo-uracil with Sodium Diphenylphosphide  | | | | Abstract
| 5-Bromo-uracil (1) reacts with sodium diphenylphosphide or a mixture of sodium diphenylphosphide and sodium amide in liquid ammonia to give sodium 5-bromo-uracilate (5 a). From water 5 a crystallizes with one mole H2O yielding 5b. Treatment of 5 a with D2O yields sodium 5-bromo-N-deutero-uracilate-D20 (1/1) (5 c). With chlorodiphenyl-phosphine 5a forms 1-diphenylphosphino-uracil (2). 5a, b, c show N(l)-N(3)-(H/D)-tauto-merism in concentrated D2O solutions already, but in DMSO or Dö-DMSO only in dilute solutions. All the compounds were characterized by infrared, Raman, X H NMR, UV spectra and conductometry. | | | |
