The reaction of (CMe)AnCl (An = Th, U) with 2.8 or 4 equivalents of LiNMe, respectively, affords (CMe)An(NMe) in high yields. In addition to improved syntheses, the solid-state structures, voltammetric data, and UV-visible-NIR spectra for these classic actinide bis(dimethylamido) complexes are presented for the first time.

Trimethyltin fluoride (Me 3 SnF) is a mild and selective reagent for the installation of actinide fluoride bonds as demonstrated by the room temperature synthesis of a variety of organometallic and inorganic thorium(IV), uranium(IV), and uranium(V) fluoride complexes {(1,2,
