Abstract

Results of high-pressure NMR investigations of subcritical and supercritical-fluid solutions of metal complexes in ethylene and C02 are presented. To our knowledge, this is the first report of high-pressure NMR studies of metal chelates in supercritical fluids. Examples presented include 19F NMR studies of two β-diketone metal chelates dissolved in subcritical CO2-methanol mixtures and a 1H NMR study of the (1,5-cyclooctadiene) dimethylplatinum (II) (Pt-COD) complex in supercritical ethylene. High-pressure NMR chemical shifts as a function of density for supercritical ethylene are also presented. The results show the utility of the NMR technique to study a variety of metal complexes in subcritical and supercritical fluids.
