Bulkily substituted organodihydrogermylium and -stannylium cations [ArEH ] (E=Ge, Sn; Ar=2,6-Trip C H , Trip=2,4,6-triisopropylphenyl) were characterized as salts of the weakly coordinating perfluorinated alkoxyaluminate anion [Al{OC(CF ) } ] . 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 sp CH unit of the 1,2-difluorobenzene solvent.
大体积取代的有机二氢化锗和锡鎓阳离子[ArEH]（E=Ge，Sn；Ar=2,6-Trip C H，Trip=2,4,6-三异丙基苯基）被表征为弱配位全氟烷氧基铝阴离子[Al{OC(CF 3 )}]的盐。在室温下，锡鎓阳离子释放氢气生成低价有机锡阳离子[Ar*Sn]。相比之下，二氢化锗阳离子将氢原子转移到三联苯配体的芳基部分，并在氢气或 1,2-二氟苯溶剂的 sp CH 单元的氧化下加成氢。
