Preparation and hydrogen-deuterium exchange of alkyl and hydride bis(trimethylsilyl)amido derivatives of the actinide elements
The monomeric, hydrocarbon-soluble monohydrides and monodeuterides of the actinide metals (thorium or uranium) of the type HM(N(SiMe/sub 3/)/sub 2/)/sub 3/ have been prepared. Their reaction chemistry - n-BuLi followed by MeBr yields MeM(N(SiMe/sub 3/)/sub 2/)/sub 3/ and borane in tetrahydrofuran yields BH/sub 4/M(N(SiMe/sub 3/)/sub 2/)/sub 3/ - suggests that the hydrogen atom is hydridic. Pyrolysis of the hydrides yields the novel, four-membered ring metallacycle ((Me/sub 3/Si)/sub 2/N)/sub 2/MCH/sub 2/Si(Me)/sub 2/NSiMe/sub 3/ where M is Th or U. These metallacycles are the key intermediates in the hydrogen-deuterium exchange reaction that yields ((CD/sub 3/)/sub 3/Si)/sub 2/N)/sub 3/MD.
