Vapor-phase iodoacetic acid is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 18 days(SRC), calculated from its rate constant of 8.9X10-13 cu cm/molecule-sec at 25 °C(SRC) that was ...
37. 5-FU reacted with α-chloroacetic acid in the presence of potassium hydroxide (KOH) and water at 60 °C (Scheme 2). The 5 h reaction yielded 83% of 5-FA. Nuclear magnetic resonance (NMR) spectroscopy and electrospray ionization-high resolution mass spectrometry (ESI-HRMS) were used ...
Co-evaporate the reaction mixture with toluene to remove the remaining acetic anhydride, pyridine and acetic acid, dilute the syrupy mixture with ethyl acetate, and wash with 2 M HCl aq. (200 ml) and water. The aqueous layer should be washed once with ethyl acetate, and then wash the...
