Abstract
The high-resolution fluorine-19 n.m.r. spectra of several polyfluoroaromatic compounds and of derived transition-metal complexes are presented and discussed. Substituent shielding parameters are tabulated for many commonly encountered functional groups, and details of the identification of complex products from the reaction of the anion [(π-C5H5)Fe(CO)2]– with C6F5CN, 1,2-C6F4I2 and C6F5Br are given. The nature of the complexes formed has been confirmed by use of high-resolution mass-spectrometric techniques in the latter two cases.Keywords
