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 {(1,2,4‐ t Bu 3 C 5 H 2 ) 2 ThF 2 , (C 5 Me 5 ) 2 U(F)(O‐2,6‐ i Pr 2 C 6 H 3 ), U(F)(O‐2,6‐ t Bu 2 C 6 H 3 ) 3 , U(F)[N(SiMe 3 ) 2 ] 3 , (C 5 Me 5 ) 2 UF 2 (L) (L = O=PMe 3 , O=PPh 3 , O=PCy 3 ), and (C 5 Me 5 ) 2 U(F)(=N‐2,6‐ i Pr 2 C 6 H 3 )} from their corresponding chloride, bromide, and iodide analogues. From these reactions, the new (C 5 Me 5 ) 2 UF 2 (L) (L = O=PPh 3 , O=PCy 3 ) uranium fluoride complexes were isolated and characterized by NMR spectroscopy and X‐ray crystallography.
