The monomeric, hydrocarbon-soluble monohydrides and monodeuterides of the actinide metals (thorium or uranium) of the type HM[N(SiMe₃)₂]₃ have been prepared for this research. Their reaction chemistry, n-BuLi followed by MeBr yields MeM[N(SiMe₃)₂]₃ and borane in tetrahydrofuran yields BH₄M[N(SiMe₃)₂]₃, suggests that the hydrogen atom is hydridic. Pyrolysis of the hydrides yields the novel, four-membered ring metallocycle [(Me₃Si)₂N]₂MCH₂Si(Me)₂NSiMe₃ where M is Th or U. In conclusion, these metallocycles are the key intermediates in the hydrogen-deuterium exchange reaction that yields {[(CD₃)₃Si]₂N}₃MD.
