Stille CC-couplings in supercritical CO2 (scCO2) were performed with perfluoro-tagged and un-tagged Pd complexes in high yields. With fluoro-tagged complexes yields were generally slightly higher. A recycling of the perfluoro-tagged catalyst was also achieved.
The propensity of highly pyramidalized unsaturated dodecahedranes (1, 11, 13) for metal complexation has been tested; structures, complexing strengths and reversibility have been analyzed by IR, 1 H, 13 C, 31 P, 195 Pt NMR, Moszbauer measurements and crystal structure analysis.
