| Abstract: | Bulkily substituted organodihydrogermylium and -stannylium cations [Ar*EH2]+ (E=Ge, Sn; Ar*=2,6-Trip2C6H3, Trip=2,4,6-triisopropylphenyl) were characterized as salts of the weakly coordinating perfluorinated alkoxyaluminate anion [Al{OC(CF3)3}4]−. At room temperature, the stannylium cation liberates hydrogen to generate the low valent organotin cation [Ar*Sn]+. In contrast, the dihydrogermylium cation transfers the hydrogen atoms to an aryl moiety of the terphenyl ligand and oxidatively adds either hydrogen under an atmosphere of hydrogen or a sp2 CH unit of the 1,2-difluorobenzene solvent. |
