    Notes: Reaction of 3-aminopyrazole (1) with chloroacetyl chloride gives a mixture of 3-amino-1- and -2-(chloroacetyl)pyrazole (2 and 3), both of which rearrange in the solid-state to 3-(chloroacetamido)pyrazole (4) over a period of a few days. The course of the rearrangements was monitored directly by CP/MAS NMR and indirectly by 1H NMR spectroscopy; the results suggest that the mechanism involves 3 → 2 → 4.

    NMR visibility of 35Cl- in human erythrocytes (1995)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 33 (1995), S. 66-69

    Notes: Contrary to previous reports, Cl- is visible by 35Cl NMR inside human erythrocytes. In spectra run at 49.01 MHz the intracellular chloride has a linewidth at half-height of ca 700 Hz and shows double Lorentzian character. Mn2+ was used to relax the extracellular 35Cl- to allow the intracellular 35Cl- to be seen. The experimental protocol described should allow NMR observation of anion transport rates in human erythrocytes.
