Abstract

Recently, a procedure based on the pattern recognition of 2D NMR contours was described for the study of molecules containing fluorines. With the use of a two-dimensional NMR experiment involving the chemical-shift correlations of proton and carbon-13 resonances, it is possible to derive all the basic information about fluorines without actually performing ¹⁹F NMR. The technique utilizes the distinctive nature of contour patterns in the 2D plot for the identification of the position of fluorines in the molecule.
