It is shown that the deprotonation of bulky amides such as HN(SiMe 2 Ph) 2 may be accelerated by the use of catalytic quantities of an alkali metal tert-butoxide salt, affording, for example, overnight syntheses of NaN(SiMe 2 Ph) 2 . The new uranium(IV) and uranium(III) complexes [U{N(SiMe 2 H) 2 } 4 ] and [U{N(SiMe 2 Ph) 2 }...
