New uranyl derivatives featuring the amide ligand, -N(SiHMe2)tBu, were synthesized and characterized by X-ray crystallography, multinuclear NMR spectroscopy, and absorption spectroscopies. Steric properties of these complexes were also quantified using the computational program Solid-G. The increased basicity of the free ligand -N(SiHMe2)tBu was demonstrated by direct comparison to -N(SiMe3)2, a popular supporting ligand for uranyl. Substitutional lability on a uranyl center was also demonstrated by exchange with the -N(SiMe3)2 ligand. The increased basicity of this ligand and diverse characterization handles discussed here will make these compounds useful synthons for future reactivity.

Reaction of nuclear-chemically generated ethylsilylium ions with trimethyl(rert-butylamino)silane in the gas phase was studied. In the course of reaction the ethylsilylium ion completely isomerizes into the dimethylsilylium ion. Experiments show that the pathway involving proton transfer practically is not realized, in contrast to the reactions of carbenium ions with amines.
