Alkane and amine elimination

This type of reaction that makes use of the well-known acidic character of [CpjReH] [27] was subsequently adapted to the formation of U-Re bonds via alkane and amine elimination. While in the first case a substituted tren ligand was applied in an elegant intramolecular alkane elimination [28], the second example stems from the amides [(ts > )U(thf),(NR2)] ( = 1, R = Cyt = 0, R = SiMe3) (Scheme 3.10) [29]. Again, tripodal ligands were helpful in stabilizing the coordination sphere at uranium vide supra).
